Question

How many moles are in 199 grams of CCl4 (molar mass =153.82g/mol)

Answer 1

mol CCl4 = 1.294 mol

moles (n) = (mass)/(molar mass)

mass = 199 g CCl4

molar mass = 153.82 g/mol

nCCl4 = 199 gCCl4 / 153.82 g/mol

nCCl4 = 1.294 mol CCl4

Answer 2

mol CCl4 = 1.294 mol

Step-by-step explanation:

• moles (n) = (mass)/(molar mass)

∴ mass = 199 g CCl4

∴ molar mass = 153.82 g/mol

⇒ nCCl4 = 199 gCCl4 / 153.82 g/mol

⇒ nCCl4 = 1.294 mol CCl4
