One mole of cobalt weighs 58.9 grams. Hence the mass in grams of 345 moles of cobalt is 20320.5 g.
What is cobalt?Cobalt is 27th element in periodic table. It is place in d- block of periodic table and is termed as transition metal. Transition metals sows variable oxidation states.
The atomic number of cobalt is 27. Thus, it contains 27 protons and 27 electrons. The mass number is 57. The mass of a given number of moles of an element can be calculated by multiplying its atomic mass by number of moles.
The atomic mass of cobalt = 58.9 g/mol
The mass of one mole of cobalt is 58.9 g/mol.
Thus, the mass of 345 moles of cobalt is calculated as follows:
mass of 345 moles of Co = 345 mol × 58.9 g/mol = 20320 g.
Therefore, the mass of cobalt in 345 moles is 20320 grams.

water is a ____ molecule meaning the positive hydrogen end attracts the negative oxygen ends of another
A. balance
B.universal
C. wet
D.polar
please answer! will give brainliest
Answers
Water is a polar molecule where, the positive hydrogen end attracts the negative oxygen ends of another water molecule. Thus, option D is correct.
What is polarity ?Polarity is ability of charge separation in a molecule. In some molecules, the positive and negative ends exists separately and both ends remains reactive towards the counter charged end of other molecule.
The charge separation in molecules results in a dipole moment. Permanent dipole moment make the molecule polar. Water is a polar molecule.
The shared pair of electrons in water are more attracted towards the electronegative oxygen atom leads the charge separation. This polarity helps to the formation of strong intermolecular hydrogen bonding.

Calculate the pH of a 0.187 M solution of a base that has a Kb = 5.86x10^-6
Answers
Answer:
[tex]pH=11[/tex]
Explanation:
Hello there!
In this case, since the ionization of the described base is:
[tex]base+H_2O\rightarrow OH^-+baseH^+[/tex]
Thus, the equilibrium expression in terms of the reaction extent is:
[tex]Kb=5.86x10^{-6}=\frac{x^2}{0.187-x}[/tex]
Thus, by solving for x we obtain:
[tex]5.86x10^{-6}({0.187-x})=x^2\\\\1.10x10^{-6}-5.86x10^{-6}x-x^2=0[/tex]
So the values of x are:
[tex]x_1=0.0010M\\x_2=-0.0010M[/tex]
So the feasible answer is 0.0010 M, thus we compute the pOH:
[tex]pOH=-log(0.0010M)=3[/tex]
And therefore the pH:
[tex]pH=14-pOH=14-3\\\\pH=11[/tex]

A tank of gas is found to exert 8.6 atm at 38°C. What would be the required
temperature to change the pressure to standard pressure?
Answers
Answer:
36.2 K
Explanation:
Step 1: Given data
Initial pressure of the gas (P₁): 8.6 atmInitial temperature of the gas (T₁): 38°CFinal pressure of the gas (P₂): 1.0 atm (standard pressure)Final temperature of the gas (T₂): ?Step 2: Convert T₁ to Kelvin
We will use the following expression.
K = °C +273.15
K = 38 °C +273.15 = 311 K
Step 3: Calculate T₂
We will use Gay Lussac's law.
P₁/T₁ = P₂/T₂
T₂ = P₂ × T₁/P₁
T₂ = 1.0 atm × 311 K/8.6 atm = 36.2 K

Taking into account the definition of the Arrhenius theory of acids and bases, the correct answer is option B. "Bases increase the concentration of hydroxide ions [OH⁻]"
Arrhenius theory of acids and basesAn Arrhenius acid is defined as chemical substances that contain hydrogen, and that when dissolved in water produce a concentration of hydrogen ions or protons (H⁺), increasing the concentration of H⁺ in the solution.
That is, according to Arrhenius theory, an acid is a substance that dissociates H⁺ ions in aqueous solution.
On the other hand, according to this Theory, a Arrhenius base is any substance that, when dissolved, releases hydroxyl ions (OH⁻).
SummarySo, the correct answer is option B. "Bases increase the concentration of hydroxide ions [OH⁻]"

79.2 L of a gas are contained at STP. How many moles are present in the container?
Answers
Answer:
3.54 mol
Explanation:
When at STP (Pressure of 1 atm & T of 273.16 K), one mol of any given gas occupies 22.4 liters.
With the above information in mind we can calculate the number of moles, using the factor 22.4 L/mol:
79.2 L ÷ 22.4 L/mol = 3.54 mol
There are 3.54 moles of the gas present in the container.
