MCQ : 0.10 mol of carbon is equivalent to

Question

0.10 mol of carbon is equivalent to

1. 1.2 g of carbon
2. 1\over 12 g of carbon
3. 12.0 g of carbon
4. 0.1 g of carbon

Answer

1.2 g of carbon

Explanation

To determine the mass of 0.10 mol of carbon, we need to know the molar mass of carbon. The molar mass of carbon is 12.0 g/mol, which is the average atomic mass of carbon taking into account its isotopes.

Using the molar mass of carbon, we can calculate the mass of 0.10 mol of carbon:

m = n × M

= 0.10 × 12.0 = 1.20 g
