Question

How many particles are in 1.43 g of a compound with a molar mass of 233? (No molar mass calculation needed) (show work plz)

Answer 1

Step-by-step explanation:

mol = given mols / molar mass

given mass = 1.43 grams

molar mass = 233

mols = 1.43 / 233 = 0.00614

1 mol contains 6.02 * 10^23 particles

0.00614 moles = x Cross multiply

1*x = 0.00614 * 6.02*10^23

x = 3,68 * 10^21 particles.
