Answer:

0.0342 mol

Explanation:

The molar mass of boron is 10.81 g/mol, that is, 1 mole of boron (6.02 × 10²³ molecules of boron) has a mass of 10.81 grams. This is the ratio that we will use to find the number of moles in 3.70 × 10⁻¹ g, using a conversion fraction.

3.70 × 10⁻¹ g B × (1 mol B / 10.81 g B) = 0.0342 mol B
