If 355 g Al(NO3)3 reacts with an excess of K2CrO4, how many moles of KNO3 would be produced?
chemistry
3.50 mol Al(NO3)3 reacts with 5.00 mols K2CrO4, the total number of moles of Al2(CrO4)3 and KNO3 would be? Here is the equation if it's needed. 2 Al(NO3)3(aq) + 3 K2CrO4(aq) → Al2(CrO4)3(s) + 6 KNO3(aq)
Chemistry
How many atoms of O are in 4 moles of (NH4)3PO4 - 6H2O? The answer is 2.41x10^25 I have no clue how to arrive at this answer.
