Answer:

$604.35 \times 10 {}^{22} kg$

Step-by-step explanation:

$total \: mass \: = 5.97 \times 10 {}^{24} \: kg \: + \: 7.35 \times 10 {}^{22} kg$

$= 5.97 \times 100 \times 10 {}^{22} + 7.35 \times 10 {}^{22}$

$= 597 \times 10 {}^{22} + 7.35 \times 10 {}^{22}$

$= (597 + 7.35) \times 10 {}^{22}$

$= 604.35 \times 10 {}^{22} kg \:$
