How many grams of hydrogen are needed to produce 10 moles of H3PO4?

JAYACHAUDHARY1: yups

JAYACHAUDHARY1: yeah most important

wolf007: Mains you can clear easily if you are good in solving ncert ques

wolf007: just for advance level u need to work hard a bit

wolf007: I wont say its easy but not hard too

wolf007: my pleasure :)

P4O10(s)+6H2O(l)→4H3PO4(aq)

Let's now find the relative number of moles of phosphoric acid (H3PO4) using the coefficients of the equation, and the fact that 10.0 mol H2Oreact:

10.0mol H2O(4lmol H3PO46mol H2O)=6.67 mol H3PO4

Now, using the molar mass of H3PO4 (calculated to be 98.00 g/mol), let's find the theoretical mass of phosphoric acid produced:

6.67lmol H3PO4(98.00lg H3PO41mol H3PO4
