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

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
$d = \frac{m}{v}$

2) Now substitute the variables for their actual values:
$d = \frac{119}{30}$

3) Calculate by dividing:
$d = 3.96666666 \ldots$

$d = 4$(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!
