Question

How many grams are in 4.63 x 1024 molecules of CCl4?

Answer 1

Answer:

$m=1,182.8g$

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:

$mol=4.63x10^{24}molec*\frac{1mol}{6.022x10^{23}molec}=7.69mol$

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

$m=7.69mol*\frac{153.81g}{1mol} \\\\m=1,182.8g$

Best regards!
