27.0 g
Explanation:
The density of a substance tells you the mass of exactly one unit of volume of said substance.
In your case, aluminium is said to have a density of
density Al
=
2.70 g
.
cm
−
3
This tells you that every
1 mL
of aluminium has a mass of
2.70 g
.
All you have to do now is use the density of aluminium as a conversion factor to go from cubic centimenters of aluminium to grams

The answer is rounded to three sig figs.
Using previously given equation, the estimate of the GPA of a student who studies for 15 hours a week is; 3.1
<h3>How to predict an equation?</h3>
The equation here is probably a "best fit" equation based upon given data which is GPA versus the number of hours of study per week.
Now, the equation of best fit is given as;
y = 0.149x + 0.89
Thus, if the number of study hours of interest is 15, then the GPA is;
GPA = 0.149(15) + 0.89
GPA = 3.1
