Question

100 g of dihydrogen and 150 g of dioxygen combines to form water. Find the mass of water formed. pls done this question step by step ​

Answer 1

Answer:

2H2 + o2 = 2 H2O

moles of hydrogen = 100/2 =50

moles of oxygen = 150/32 =4.68

so here oxygen is limiting reagent

1 mole o2 gives 2 mole H2O

4.68 mole give 2×4.68 mole H2O

mass of H2O = 2×4.68×18= 168.75

Answer 2

Explanation:

168.75 is the correct answer
