Question

How to solve stoichiometric problems easily ??​

Answer 1

Answer:

knowing the number of moles helps you. Also molar mass.

Explanation:

for example,

CH4+2O2----->CO2 + 2H2O

i/

stoichiometric coefficients

CH4 - 1

O2 - 2

CO2 - 1

H2O - 2

ii/

Mole-mole relationship

CH4 - 1 mole

O2 - 2 moles

CO2 - 1 mole

H2O - 2 moles

iii/

Mass- mass relationship= no. of mole× molar mass,

CH4 - 1 mol×16 g 1/mol =16 g

O2 - 2 mol × 32 g 1/mol= 64 g

CO2 - 1 mol× ......

iv/

Mass volUme relation ship= no. of mole× molar mass of reactant

CH4 - 16 g

O2 - 64 g

CO2 - 22.4 L

H2O - 44.8L

knowing these things will help you to solve problems based on stoichiometry.

ALL THE BEST!

Hope it helps you.
