Answer:

Since rocks are denser than water, the water level will drop. The rocks in the boat will displace nearly the same amount of water as the rocks once thrown overboard. The difference would be the amount of water displaced by the boat itself and the person in it. Mass is mass whether in the water or the boat.

Answer:

Explanation:

first, you calculate the amount of O2 in moles:

98.0 ÷ 32 = 3.0625

second, the ratio if O2/C3H8 is 5 so you need to calculate O2 in moles with that:

3.0625 ÷ 5 = 0.6125

third, the amount of CO2 in moles also can be calculate by the ratio of C3H8/CO2 which is 3

0.6125 × 3 = 1.8375

then multiply CO2 in moles by its molar mass which is 44 g/mol

1.8375 × 44 = 80.85g
