Answer:
Step-by-step explanation:
7.3×10^22 = 73,000,000,000,000,000,000,000
73,000,000,000,000,000,000,000 × 26,000,000 = 1,898,000,000,000,000,000,000,000,000,000 or 1.898 × 10^30
water freezes in 32 degrees
so 32-5=27
so it was 27 degrees bellow the freezjng point of water
7 groups
Each group would have 1 blue marble and 3 green marbles
