How many molecules are in 3.9 moles of water?
A. 2.3 x 1024 molecules of water
B. 6.5 x10-24 molecules of water
C. 71 molecules of water
D. .22 molecules of water

Respuesta :

We know, number of molecules in 1 mole = 6.23 * 10²³
In 3.9 moles, it would be: 3.9 * 6.23 * 10²³
= 23 * 10²³
= 2.3 * 10²⁴

In short, Your Answer would be Option A
