Solution A has a mass of 60g and solution B has a mass of 40g. When they are mixed a chemical reaction occurs and a gas is produced. If the mass of the product is 85g, what mass of gas was produced.
I think the answer is 15g, but I'm not sure.
Please correct me or confirm that my answer is correct.
Thank you.

Since mass is never lost, when you mix the two Solutions, the mass should be 100g, except a chemical change occured. Even though, the total of all things created (gas) combined with what's left should equal the original. So, since 100g - 85g, the mass of the gas would be 15g :)

Yes, it's 15 grams, since the Conservation of Mass Law states that mass is neither created nor destroyed. Therfore, if the mass of the product is 85 grams, the mass of the gas would be 100g-85g=15g. Hope this helps!

You are correct. Remember, the law of conservation of mass. In the problem, the total mass is 100g. The products mass must equal 100g. Since the first product has a mass of 85 then the remaining mass of 15g is the gas.

A + B = C (s) + D (g)
60 g + 40 g = 85 g (s) + (100 - 85 =) 15 g (g)
yeh, you are correct, the mass of the gas is 15 g
