Silicon (si) is used in the semiconductor industry. how many grams of si correspond to 10 mol of si? help pls
I will mark the brainless

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

just took the test;

argument: "it's time to wage a war against britain to secure american freedom."

claims: "america has tried every peaceful method available for seperating from england" & "the americans' petitions to the king have been turned away by him."
