Question

According to the law of Conservation of Mass, the amount of mass in the product must equal the amount of mass in the reactants. With this in mind, A student mixed two clear liquids together in a beaker. A gas and a new liquid formed. The gas escaped, so the student was unable to measure its mass. She guessed that its mass was no more than 10.0 grams. Her data is shown in the table below. Is the student's guess about the mass of the gas correct?

Answer 1

A. Yes, the actual mass is 4.8 g.
B. Yes, the actual mass is 9.0 g.
C. No, the actual mass is 13.8 g.
D. No, the actual mass is 17.2 g.

Answer 2

The mass of the escaped gas must equal the amount of mass lost from the liquid.

How much mass did the two liquids have before the student mixed them?

Answer 3

I dont know it dosn't say

Answer 4

The table gives the mass of Reactant A and Reactant B- those are what you're looking for.

Answer 5

o thnx

Answer 6

The difference in mass between those two reactants and the total mass of the product is how much mass was lost. How much is that?

Answer 7

9.0 right

Answer 8

The mass of the first reactant is 22.0 and the mass of the second reactant is 9.0, which gives you a total mass of 31.0g.

Subtracting the mass of the resulting liquid solution from 31.0 grams will give you the amount of liquid that was turned into a gas.
