We are given initially with 1.2 x 1024 molecules of water, added further with <span>5.0 moles of water. we are asked to determine the total number of molecules of water after the addition. We just </span> convert the number of moles to number of molecules. 5 moles of water is equal to 3.011x 10^24 molecules. The total number is that we add the initial and the additional, equivalent to 4.211 x10^24 molecules.
Scientists use models to study atoms because so they can prove that their experiment(s) are right/make sense. :)
It usually holds more water because of evaporation and makes the earth very hot.
Answer:
sorry i never learned this
Explanation:
Answer:
0.0522 mol NaSo4
Explanation:
3.148 x 10^22 Formula units NaSo4 * 1 mol NaSo4 / 6.02 x 10^23 Formula units NaSo4 = 0.0522 mol NaSo4
