Question

1. a sample of an alloy (density = 9.62 g/cm³) was submerged in a graduated cylinder containing water. the water level in the cylinder rose from 166.5 cm³ to 182.0 cm³. how many grams did the sample weigh?

0.621 g
175 g
18.9 g
17.8 g
149 g

Explanation:

Step1: Calculate sample volume

$V = 182.0\ \text{cm}^3 - 166.5\ \text{cm}^3 = 15.5\ \text{cm}^3$

Step2: Calculate sample mass

$m =
ho \times V = 9.62\ \text{g/cm}^3 \times 15.5\ \text{cm}^3$

Answer:

149 g
