Question

question 1 (1 point)
which one of the following substances will float in gasoline, which has a density of 0.66 g/ml?
a) aluminum (density = 2.70 g/ml)
b) table salt (density = 2.16 g/ml)
c) mercury (density = 13.6 g/ml)
d) sugar (density = 1.59 g/ml)
e) balsa wood (density = 0.16 g/ml)

Explanation:

To determine which substance floats in gasoline (density = 0.66 g/mL), we use the principle that a substance floats if its density is less than that of the liquid it is placed in. We compare the density of each option to 0.66 g/mL:

• A) Aluminum: 2.70 g/mL > 0.66 g/mL (sinks)
• B) Table salt: 2.16 g/mL > 0.66 g/mL (sinks)
• C) Mercury: 13.6 g/mL > 0.66 g/mL (sinks)
• D) Sugar: 1.59 g/mL > 0.66 g/mL (sinks)
• E) Balsa wood: 0.16 g/mL < 0.66 g/mL (floats)

Answer:

E. balsa wood (density = 0.16 g/mL)
