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

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

Step2: Calculate sample mass

$\text{Mass} = \text{Density} \times \text{Volume} = 9.62\ \text{g/cm}^3 \times 15.5\ \text{cm}^3$
$\text{Mass} = 149.11\ \text{g} \approx 149\ \text{g}$

Answer:

$\square$ 149 g
