Question

1. a gold necklace has a density of 18 grams per cubic centimeter and a volume of 1.5 cubic centimeters. calculate its mass. 2) write your answer as a whole number. 3) ____ grams

Explanation:

Step1: Recall density-mass formula

The formula relating density ($
ho$), mass ($m$), and volume ($V$) is $m =
ho \times V$.

Step2: Substitute given values

$
ho = 18 \frac{\text{g}}{\text{cm}^3}$, $V = 1.5 \text{cm}^3$. Substitute into the formula:
$m = 18 \times 1.5$

Step3: Calculate and round to whole number

$18 \times 1.5 = 27$

Answer:

27 grams
