Question

A gold necklace has a mass of 40grams and a volume of 2cubic centimeters. What is its density?

Answer 1

Answer:

density = mass (kg) * volume (cu m)

so here you have to first convert 40g into kg and 2 cm^3 into cubic m

so it's

 0.04 kg * 0.02m

= 0.008 kg/m^3 (ans)

Answer 2

Answer:

20

Step-by-step explanation:

You know the mass and volume of the gold necklace. Use the equation to find its density.

density = mass ÷ volume

First, replace mass and volume with the given values.

density = 40grams ÷ 2cubic centimeters

Then, solve the equation.

40grams ÷ 2cubic centimeters = 20gramspercubic centimeter

The gold necklace has a density of 20gramspercubic centimeters.
