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=119119 grams
V=3030 mL

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

2) Now substitute the variables for their actual values:
d=119/30d=11930

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!
