Answer:
mass composition is very essential in obtaining a balanced equation
Explanation:
to have a completely balanced equation that means the right hand side being your reactants must be equal to the right hand side being your product. both sides need to have equal mass composition, when calculating the mass composition make sure both sides are equal if not consider revisiting the number of moles on both sides to ensure they all balance

To determine the molar mass of the unknown gas, we use Graham's Law of Effusion where it relates the effusion rates of two gases with their molar masses. It is expressed as r1/r2 = √M2/M1. We calculate as follows:
Let 1 = argon gas 2 = unknown gas
r2 = 0.91r1r1/r2 = 1/0.91
1/0.91 = √M2/M1 = √M2/40M2 = 48.30 g/mol
Answer:
1gram of water
Explanation:
First balance the equation
Ch4+2O2>CO2+2H2O
Ratio is 1:2
500×10-3what about 2?
500×10-3×2=1g
1g of water
