Answer: The molarity of this solution is 2.5 M.

Explanation:

Given : [tex]V_1 = 44 mL[/tex],           [tex]V_2 = 176 mL[/tex]

[tex]M_1 = 10 M[/tex]

Therefore, the value of molarity of the solution is calculated using following formula.

[tex]M_1 \times V_1 = M_2 \times V_2[/tex]

Substitute the values into above formula as follows.

[tex]M_1 \times V_1 = M_2 \times V_2\\10 M \times 44 mL = M_2 \times 176 mL\\M_2 = \frac{10 M \times 44 mL}{176 mL}\\= 2.5 M[/tex]

Hence, molarity of the solution is 2.5 M.

Answer:

molar mass of N + 3 × molar mass of H

Explanation:

took the test and got it right

Molar mass is the proportion of the mass of the substance to the moles. The molar mass of ammonia is calculated as, the molar mass of N + 3 × molar mass of H. Thus, option c is accurate.

The molar mass of any substance is the mass in grams divided by the mole of the substance. It is given in g/mol. It is calculated as:

Molar mass = Mass ÷ Moles

In Ammonia there are one nitrogen and three hydrogen atoms, and hence the molar mass is given as,

Molar mass of N + 3 × Molar mass of H

Therefore, option c. molar mass of N + 3 × molar mass of H is correct.

Answer:

74.99g

Explanation:

Mass of a substance can be calculated by using the formula;

mole = mass ÷ molar mass

mass = molar mass × mole

According to this question, 37.2 moles of hydrogen gas is given.

Molar mass of hydrogen gas (H2) = 1.008(2) = 2.016g/mol

mass = 2.016 × 37.2

Mass of H2 = 74.995

Mass = 74.99g

Answer:

3.04 mol NH3* (17.03 g NH3/ 1 mol NH3)= 51.8 g NH3~

The mass in grams of 3.04 mol of ammonia vapor is 51.68g

The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter.

A mole is defined as the amount of substance containing the same number of atoms, molecules, ions, etc. as the number of atoms in a sample of pure 12C weighing exactly 12 g.

Given,

Moles of ammonia = 3.04 moles

Molar mass of ammonia = 14 + 3 = 17

Moles = mass / molar mass

Mass = moles × molar mass

= 3.04 × 17

= 51.68 g

Therefore, mass in grams of 3.04 mol of ammonia vapor is 51.68g

Answer:

A) The substance is in the gas phase only in "region 5".

B) The substance is in both the liquid and solid phase in "region 2"

C) The substance is only in the liquid phase in "region 3".

D) The melting point is the temperature at "region 2".

E) The boiling point is the temperature at "region 4".

Explanation:

The graph is a graph of the solid, liquid, vapour phase change diagram.

In phase 1, the substance is ice which is the solid phase.

In phase 2,it undergoes melting in a forward reaction.

In phase 3, the melting from phase 2 has now changed to water which is liquid phase.

In phase 4, the substance is undergoing a forward reaction known as evaporation.

In phase 5, the evaporation from stage 4 will turn the liquid into vapour known as the gas phase.

A) The substance is in the gas phase only in "region 5".

B) The substance is in both the liquid and solid phase in "region 2"

C) The substance is only in the liquid phase in "region 3".

D) The melting point is the temperature at "region 2".

E) The boiling point is the temperature at "region 4".

Answer:  233 L of [tex]CO_2[/tex] will be produced from 150 grams of  [tex]C_4H_{10}[/tex]

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]  [tex]\text{Moles of} C_4H_{10}=\frac{150g}{58g/mol}=2.59moles[/tex]

The balanced chemical equation is:

[tex]2C_4H_{10}+13O_2(g)\rightarrow 8CO_2+10H_2O[/tex]  

According to stoichiometry :

2 moles of [tex]C_4H_{10}[/tex] produce =  8 moles of [tex]CO_2[/tex]

Thus 2.59 moles of [tex]C_4H_{10}[/tex] will produce=[tex]\frac{8}{2}\times 2.59=10.4moles[/tex]  of [tex]CO_2[/tex]  

Volume of [tex]CO_2=moles\times {\text {Molar volume}}=10.4moles\times 22.4mol/L=233L[/tex]

Thus 233 L of [tex]CO_2[/tex] will be produced from 150 grams of  [tex]C_4H_{10}[/tex]

Answer: The temperature at pressure of 635.7 kPa is [tex]2033^0C[/tex]

Explanation:

The combined gas equation is,

[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]

where,

[tex]P_1[/tex] = initial pressure of gas = 107.4 kPa

[tex]P_2[/tex] = final pressure of gas = 635.7 kPa

[tex]V_1[/tex] = initial volume of gas = [tex]515cm^3[/tex]

[tex]V_2[/tex] = final volume of gas = [tex]644cm^3[/tex]

[tex]T_1[/tex] = initial temperature of gas = [tex]38.6^0C=(38.6+273)K=311.6K[/tex]

= final temperature of gas = ?

Now put all the given values in the above equation, we get:

[tex]\frac{107.4\times 515}{311.6}=\frac{635.7\times 644}{T_2}[/tex]

[tex]T_2=2306K=(2306-273)^0C=2033^0C[/tex]

The temperature at pressure of 635.7 kPa is  [tex]2033^0C[/tex]
