Question

If 48.1 g of solid Al2S3 and 6.68 mL of liquid H2O are reacted stoichiometrically according to the balanced equation, how many grams of solid Al2S3 remain?

Al2S3(s) + 6H2O(l) ¡æ 2Al(OH)3(s) + 3H2S(g)

Molar Mass (g/mol)
Al2S3 150.16
H2O 18.015

H2O 0.9982
Molar Volume (L)
22.4 at STP

Gas Constant
(L.atm.mol-1.K-1)
0.0821
