I have a 489.6 gram sample of sodium sulfate decahydrate. What is the mass in grams of just water in this sample? (Don't add units, just enter the number)
Added by Michael F.
Step 1
99 (Na) * 2 + 32.06 (S) + 4 * 16.00 (O) = 142.04 g/mol Molar mass of 10H2O = 10 * (2 * 1.01 (H) + 16.00 (O)) = 180.2 g/mol Total molar mass = 142.04 + 180.2 = 322.24 g/mol Show more…
