Question

Milk of magnesia has the chemical formula Mg(OH)2. what is the mass of 3.2 moles of milk of magnesia? The molar mass of magnesium is 24.3 grams per mole.
The molar mass of hydrogen is 1.0 grams per mole. The molar mass of oxygen is 16.0 grams per mole.

A. 132.2 g
B. 135.4 g
C. 186. 6 g
D. 264. 3 g
I think its D

Answer 1

mol OH = 16+1 = 17 g/mol
sso
Mg(OH)2 = 24.3 + 34 = 58.3 g/mol
times 3.2 = 186.6
How did you get D ?
