Question

7. If carbon and oxygen combine in a definite ratio of
3:8 to form carbon dioxide what mass of oxygen gas is
required in carbon dioxide with l0g of carbon​

Answer 1

given,
C+O2 - CO2
then,
carbon:oxygen - 3:8

due to law of constant proportion, the mass ratio in which the reactants will react will remain the same.

carbon- 10g
oxygen-?

C:O2=3:8
10:02=3:8

10/O2=3/8

mass of oxygen required,
(10/3)×8
=26.6g
