Your control group would be the batteries since you CONTROL what brand you're using, for which one lasts the longest...aren't you suppose to figure that out when you do the experiment?

A single gram of 235U fuel can heat and boil 2.49 x 107 g of water. What volume of water is this?
iogann1982 [59]
You just have to convert the mass of water into volume.

To do that you use the density of water, which is about 1.0 g/ ml

So, from the formula of density D = M / V, you get V = M / D

=> V = 2.49 * 10^7 grams / 1.0 g / ml = 2.49 * 10 ^ 7 ml

You can pass that to liters using the conversion factor 1000 ml = 1 l

2.49 * 10^7 ml * 1 l / 1000 ml = 2.49 * 10^4 l = 24,900 l

Answer: 24,900 l
