Question

What is the density of an object that has a mass of 119 grams and a volume of 30 mL?

Answer 1

In order to calculate the density of an object, the density formula of d=m/v

Explanation:

In this case, you are given two facts: the mass and the volume.
M=`119` grams
V=`30` mL

Here are the steps to solving it:
1) Write formula
`d=m/v`

2) Now substitute the variables for their actual values:
`d=119/30`

3) Calculate by dividing:
`d=3.96666666...`

4) You can round your answer to one significant figure:
`d=4`(since if you round `3`, you look at tenths place. In this problem, it is `3.9` so you would round up to `4`)

5) Your answer would be `4` grams/mL

Hope this helps!
