How many grams are in 4.63 x 1024

molecules of CCl4?

Answers

Answer 1

Answer:

[tex]m=1,182.8g[/tex]

Explanation:

Hello!

In this case, since the relationship between molecules and mass is first analyzed via the Avogadro's number to compute the moles in the given molecules:

[tex]mol=4.63x10^{24}molec*\frac{1mol}{6.022x10^{23}molec}=7.69mol[/tex]

We now use the molar mass of carbon tetrachloride (153.81 g/mol) to obtain the required grams:

[tex]m=7.69mol*\frac{153.81g}{1mol} \\\\m=1,182.8g[/tex]

Best regards!

Consider the following unbalanced chemical equation representing the combustion of methane, yielding carbon dioxide and water.
CH4 + O2 --> CO2 + H20
If you had burned 800 g of methane, how many moles of Carbon dioxide would be produced?

A)122.22
B)8
C)2200
D)100
E)670

F)750
G)50

Answers

Answer:

Im pretty sure its B

Explanation:

Answer:

G) 50 mol

Explanation:

Given data:

Mass of methane = 800 g

Number of moles of CO₂ produced = ?

Solution:

Chemical equation:

CH₄ + 2O₂      →      CO₂ + 2H₂O

Number of moles of methane:

Number of moles = mass/molar mass

Number of moles = 800 g/ 16 g/mol

Number of moles = 50 mol

Now we will compare the moles of methane and carbon dioxide.

                 CH₄        :         CO₂

                    1           :          1

                  50          :        50
