A student mixed two clear liquids together in a beaker and a solid precipitate formed. His data is shown in the table below.

Liquid reactant A 10 g
Liquid reactant B 17 g
Beaker + solid product 32 g

What is the mass of the beaker?
A. 5 g
B. 10 g
C. 15 g
D. 17 g
E. 32 g

To determine the mass of the beaker, we need to subtract the combined mass of the two liquids (A and B) and the solid precipitate from the total mass of the beaker and solid product.

Given:
Liquid reactant A: 10 g
Liquid reactant B: 17 g
Beaker + solid product: 32 g

To find the mass of the beaker, we can follow these steps:

Step 1: Calculate the combined mass of the two liquids:
Combined mass of liquid reactant A and B = mass of A + mass of B
Combined mass of liquid reactant A and B = 10 g + 17 g
Combined mass of liquid reactant A and B = 27 g

Step 2: Subtract the combined mass of the two liquids and the solid precipitate from the total mass of the beaker and solid product:
Mass of the beaker = total mass of the beaker + solid product - combined mass of liquid reactant A and B
Mass of the beaker = 32 g - 27 g
Mass of the beaker = 5 g

Therefore, the mass of the beaker is 5 g, which corresponds to option A.
