Answer
The answer is below.
Work Step by Step
We first find the value of Q:
$Q_h = \frac{2\times 10^{11}}{.33}=6.06\times10^{11}$
Thus, it follows:
$Q_c= 6.06\times10^{11}-2\times10^{11}=4.06\times10^{11}$
We now find:
$ m = \frac{4.06\times10^{11}}{4184\times5}= 1.94 \times 10^7$
Thus, the answer is:
$= 1.94\times10^7-1.8\times10^7=1.4\times10^6$
