Question

If a student's unknown is a white solid and its density was calculated to be about 1.7 g/mL, it is most likely _______. A. water B. phosphoric acid C. sodium hydroxide

Answer 1

The answer to your question is letter B. Phosphoric acid

Step-by-step explanation:

A. water is not the right answer because it has a density of 1 g/ml and water is a liquid not a solid.

B. phosphoric acid is the right answer because phosphoric acid is a solid and all solids have a density higher than water (1 g/ml)

C. sodium hydroxide could be the correct answer but it is not because the crystals of sodium hydroxide are more colorless than white.
