Question

conservation of mass 12 if 37 grams of n₂ react with 73 grams of h₂, how many grams of nh₃ will be expected? *remember you can use a calculator. 37 grams of n₂ + 73 grams of h₂ → ____ grams of nh₃ © the science duo, llc

Explanation:

Step1: Recall Conservation of Mass

The law of conservation of mass states that in a chemical reaction, the total mass of reactants equals the total mass of products.

Step2: Calculate Total Mass of Reactants

The mass of \( \text{N}_2 \) is 37 grams and the mass of \( \text{H}_2 \) is 73 grams. So the total mass of reactants is \( 37 + 73 \).
\( 37 + 73 = 110 \) grams.

Step3: Determine Mass of Product

Since the total mass of reactants equals the total mass of products (from conservation of mass), the mass of \( \text{NH}_3 \) (the product) should be equal to the total mass of the reactants.

Answer:

110
