General Chemistry

Question #269198

1.6 × 10−3 mol Na2SO4.

Expert's answer

Molar mass of Na = 23 g

Molar mass of S = 32 g

Molar mass of O = 16 g

So, molar mass of "N\n\na\n\n2\n\nS\n\nO\n\n4\n\nNa_2SO_4\n\n = (2\u00d7 23 )+ 32 + (4\u00d716)g = 142 g"

Mass = "1.6\u00d710^{-3}\u00d7142=0.2272grams"
