into moles 10
gm H2O
18 gm H2 S04
20 gm
CO2
​

Answer 1

Explanation:

a) Molecular weight of oxygen in grams = 32 g of oxygen= one mole of oxygen gas

Thus, 12 g of oxygen=

32

1

×12=0.375 moles

Answer 2

Answer:

1)moles of H2O=10÷18

=0.55

2)mole of H2SO4=18÷98

=0.18

3)mole of CO2=20÷44

=0.45
