Question

at room temperature (20 °c), liquid water has a density of 1.00 g/ml and gasoline has a density of 0.670 g/ml. therefore, gasoline liquid water. when 53 ml of gasoline is placed into 1.0 l of liquid water, the gasoline will in the water.

Explanation:

Step1: Compare Densities

Density of water is $1.00\ \text{g/mL}$, density of gasoline is $0.670\ \text{g/mL}$. Since $0.670 < 1.00$, gasoline is less dense than water.

Step2: Determine Floating/Sinking

Substances less dense than a liquid will float on that liquid. So gasoline, being less dense, will float in water.

Answer:

First blank: is less dense than; Second blank: float
