Answer: 45.983 g CBr₄

Explanation:

To convert from moles to grams, you know that we will need molar mass and Avogadro's number.

Avogadro's number: 6.022×10²³ molecules/mol

Molar mass: 331.627 grams/mol

Now that we have what we need, you can use these to solve for grams. 8.35*10^2^2molecules CBr_{4} *\frac{1mol}{6.022*10^2^3molecules} *\frac{331.627 g}{1 mol} =45.983 g

Our final answer is 45.983 g CBr₄.

What is the mass of 5.50 mol of pure liquid bromine ?
GREYUIT [131]

Answer:

m Br = 439.472 g

Explanation:

mass Br = ?

∴ mol Br = 5.50 mol

∴ molar mass Br  79.904 g/mol

mass = (mol)*(g/mol)

⇒ m Br = (5.50 mol)*(79.904 g/mol)

⇒ m Br = 439.472 g
