Formula: Mass Product = (Mass Reactant / MW Reactant) × (coeff Product / coeff Reactant) × MW Product
Worked example — 244.30 g CO₂
Formula
Mass Product = (Mass Reactant / MW Reactant) × (coeff Product / coeff Reactant) × MW Product
Converts mass of one substance to the equivalent mass of another using molar masses and stoichiometric coefficients from a balanced equation.
Worked Examples
Example 1: Water to CO₂
Problem:100g H₂O, MW=18.015. Find equivalent CO₂ (MW=44.01), 1:1 ratio.
Solution:Moles = 100/18.015 = 5.551. Mass CO₂ = 5.551 × 44.01 = 244.30 g
Result:244.30 g CO₂
Frequently Asked Questions
How do I find molar mass?
Add the atomic masses of all atoms in the molecular formula. For example, H₂O = 2(1.008) + 16.00 = 18.015 g/mol.
What is a limiting reactant and how does it affect yield calculations?
The limiting reactant is the reagent that runs out first and therefore determines the maximum amount of product that can form. To identify it, convert each reactant's mass to moles, divide by its stoichiometric coefficient, and the smallest value indicates the limiting reactant. Yield calculations based on the non-limiting reactant will overestimate the actual product mass.
What is percent yield and how is it calculated?
Percent yield measures the efficiency of a chemical reaction: % yield = (actual yield / theoretical yield) × 100%. The theoretical yield is the maximum mass of product predicted by stoichiometry (what Stoichiometric Mass Converter computes). The actual yield is what is measured in the lab after the reaction. Losses from incomplete reactions, side reactions, and handling typically result in yields of 60-95% in laboratory settings.
What is the difference between mass and weight?
Mass measures the amount of matter in an object (kilograms) and is constant everywhere. Weight is the gravitational force on that mass (newtons) and varies by location. On Earth, a 1 kg object weighs about 9.8 newtons. In everyday use, the terms are often used interchangeably.
