Wyjaśnienie:
3P + 5HNO₃ + 2H₂O --> 3H₃PO₄ + 5NO
Obliczam ile to moli 200g P:
1 mol P..................31g
x moli......................200g
x = 64,52 mole P
3 mole P.................5 moli NO
64,52mola...............x
x = 107,53 mole NO
93g P................150g NO
200g...................x
322,58 g NO
93g P..............112dm³ NO
200g P...............x
x = 240,86dm³ NO
1 mol NO.............6,02*10²³ cząsteczek
107,53 mola.............x
x = 647,3*10²³ = 6,473*10²⁵ cząsteczek NO
