Asked by Baby_Banana
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 [LW1] grams. Her data is shown in the table below.
Mass (g)
liquid reactant A 22.0
liquid reactant B 9.0
liquid product 17.2
gas product ?
Is the student's guess about the mass of the gas correct?
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.
My answer is B, but I have no clue how to solve these sort of things, if it's possible, please explain this to me.
