(a) how many cubic meters of water are in a cylindrical cumulus cloud of height 3.1 km and radius 1.0 km? (b) how many 1-liter pop bottles would that water fill? (c) water has a density of 1000 kg/m3. how much mass does the water in the cloud have?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
