70.306 would be your answer.
False; animals breathe in oxygen and they produce carbon dioxide when they breathe out, and plants breathe in that carbon dioxide that the animals produce, and with that the plants create oxygen
They basically just swap oxygen for CO2, or CO2 for oxygen! So the answer is false because they DO depend on each other for the use of Oxygen and Carbon dioxide! Hope this helped :)
To find the mass you divide multiply volume and density..
Density = 1.79 x 10^-4 Volume = 6.3
(1.79 x 10^-4 )(6.3) = <span>1.1 x 10^-3 g
