Question

A student mixed two clear liquids together in a beaker and a solid precipitate formed, this data is shown in the table below . what is the mass of the beaker?

Answer 1

the mass is 10 +17 +32

Answer 2

Mass of liquid reactant A + mass of liquid reactant B = 10 g + 17 g = 27 g

Beaker + solid product = 32 g

Solve the second equation for Beaker:

Mass of beaker = 32 g - mass of solid product

Mass of beaker = 32 g - 27 g = 5 g

The beaker has a mass of 5 g.
