Question

A solid mass of 25 g is mixed with 60 g if a solution. A chemical reaction takes place and a gas is produced. The final mass of the mixture is 75 g. What is the mass of the gas released?

Answer 1

10g

Step-by-step explanation:

60+25 should equal 85, but the final mixture is not 85 grams, instead it's 75. This leads me to believe that the gas produced and released by the mixture is 10 grams, and that's where the extra mass went.
