Answer to Question #156073 in General Chemistry for Maria

Question

H₂S + NaOH --> Na₂S + H₂O

If 350ml 0.6M H₂S is reacted how many grams of Na₂S will be made?

Answer 1

H₂S + 2NaOH --> Na₂S + 2H₂O

Volume = 350ml = 0.35dm³

Mole = volume /molar volume

= 0.35dm³ / 0.6

= 0.58mol

Na₂S = 46+32 = 78gmol^-1

Mass = mole × molar mass

= 0.58mol × 78gmol^-1

= 45.24g
