Question

3.65 g of H2 and 26.7 g of O2 are mixed and reacted. How many grams of H2O are formed​

Answer 1

H2 + ½O2 = H2O

The mole of H2 = $\frac{3.65}{2}$ =1.825

The mole of O2 = $\frac{26.7}{32}$ = 0.834

here limiting regent is O2 so the number of mole of H2O formed = 2 × 0.834 = 1.668

Now Gram of H2O = 18 × 1.668 = 30.024 gram
