Answer:
281 g
Explanation:
The molar mass of a substance is the mass in grams of one mole of a substance. The molar mass is the ratio of mass of a sample to the amount of substance in that sample. The molar mass is given by the formula:
Molar mass = mass / amount in mole
The molar mass of silicon = 28.0855 g/mol. Given that amount in mol = 10 mol, hence:
Molar mass = mass / amount in mole
28.0855 = mass / 10
mass = 280.855 g
mass ≈ 281 g
