What is the formula mass of hydrated magnesium sulfate?

Chemistry
1 answer:
Masteriza [31]3 years ago
3 0

Answer:

138.39 g/mol

Explanation:

Formula mass is a synonym for molar mass, which is the sum of all the masses of the elements. These can be found on a periodic table.

Because this is hydrated, the formula needs to include H2O.

MgSO4 + H2O

Mg + S + 4O + 2H + O

24.31 + 32.07 + (4*16) + (2*1.008) + 16 = about <u>138.39</u>
