The number of moles:
3.16g of \(KMnO_{4}\)
1 mole of \(KMnO_{4}\)- 158g.
x moles of \(KMnO_{4}\)- 3.16g.
\(x=\frac{1\ mole*3.16g}{158g}=\frac{3.16}{158}=0.02\ mole\)
The number of moles:
32.33g of \(K_{2}CrO_{4}\)
1 mole of \(K_{2}CrO_{4}\)- 194g.
x moles of \(K_{2}CrO_{4}\)- 32.33g.
\(x=\frac{1\ mole*32.33g}{194g}=\frac{32.33}{194}=0.17\ mole\)
The number of moles:
100g of \(KHCO_{3}\)
1 mole of \(KHCO_{3}\)- 100.1g.
x moles of \(KHCO_{3}\)- 100g.
\(x=\frac{1\ mole*100g}{100.1g}=\frac{100}{100.1}=0.999\ mole\)
