How many moles are in 64 grams of methane, CH4?<br> A. 4<br> B. 32<br> C. 64<br> D. 13
ss7ja [257]

Answer:

A. 4.

Explanation:

  • We can use the relation:

<em>no. of moles (n) = mass/molar mass.</em>

mass = 64.0 g, molar mass = 16.0 g/mol.

∴ no. of moles (n) = mass/molar mass = (64.0 g)/(16.0 g/mol) = 4 mol.
