Question

What is the mass in grams of one mole of boron? a. 5 b. 9.012 c. 6.022 × 10^23 d. 10.811e. None of the above

Answer 1

Answer: The mass of 1 mole of boron is 10.811 grams.

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Moles of boron = 1 mole

Molar mass of boron = 10.811 g/mol

Putting values in above equation, we get:

$1mol=\frac{\text{Mass of boron}}{10.811g/mol}\\\\\text{Mass of boron}=(1mol\times 10.811g/mol)=10.811g$

Hence, the mass of 1 mole of boron is 10.811 grams.
