Question

How many grams are of sodium chlorate are present in a 2.45 mole sample?

Answer 1

260 grams sodium chlorate

Step-by-step explanation:

moles to grams multiply by formula weight.

grams to moles divide by formula weight.

sodium chlorate => NaClO₃

=> formula wt = Na + Cl + 3O = [1(23) + 1(35) + 3(16)]g/mole = 106g/mole

∴ grams NaClO₃ = 2.45 mole x 106 g/mole = 259.7 grams ≈ 260 grams

Answer 2

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles NaCl, or 58.44277 grams.
