Answer to Question #185526 in General Chemistry for Maddie Dalton

Question

BaO (s)  +  H2O (g) = Ba(OH)2 (s)  If you want to completely react 10.25 g of barium oxide, how many grams of water will you need?

Answer 1

From the equation, the ratio of barium Oxide and water is 1:1

Molar Mass of BaO = 153.33

10.25/153.33 = 0.0668 moles

Molar Mass of H₂O = 18.015

= 0.0668 × 18.015

= 1.204g
