Answer:

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!
