Answer: The mass of 1 mole of boron is 10.811 grams.
Step-by-step explanation:
To calculate the number of moles, we use the equation:
![\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}](https://img.qammunity.org/2021/formulas/chemistry/college/e4lb9duyomysx0p41hk9jd8smtfdkqfqms.png)
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* 10.811g/mol)=10.811g](https://img.qammunity.org/2021/formulas/chemistry/college/kmmg1ac9em87jw98nhdz5ba2w5egvp4lsy.png)
Hence, the mass of 1 mole of boron is 10.811 grams.
