Question

How many numbers of molecules are contained in 24 litre ccl4? density of ccl4 = 1.59 gm

Answer 1

density CCl4 is 1.59 g/mL. It isn't 1.50 g.

mass CCl4 = volume x density = 24,000 mL x 1.59 g/mL = ? grams.
Then mols CCl4 = grams CCl4/molar mass CCl4 = ?
Finally, there are 6.02E23 molecules in 1 mol of anything. Convert moles to # molecules.
