How many molecules are there in 450 grams of NaSO4?

Answer 1

Weight of NaCl used (250g)/Total molecular weight x Avagadro's number = total molecules of NaCl.

Answer 2

To find the number of molecules in 450 grams of NaSO4, we first need to calculate the number of moles using the molar mass of NaSO4 (142.04 g/mol). Then, we can use Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of molecules in the calculated moles.

Answer 3

450. g NaSO4 * (1 mol NaSO4/119.06 g NaSO4) * (6.022*10^23 Molecules NaSO4/1 mol NaSO4) = 2.28*10^24 Molecules of NaSO4

Answer 4

Divide mass by molar mass to find moles:

458(g) / 142.04(g/mol) = 3.22 mol Na2SO4
