Question

calculate the number of molecules in 180g of water.​

Answer 1

Answer:

Let the number of moles be X. 18 g of H2O = 1 mole 180 g of H2O =X

X =180/18 =10 moles.

Thus, the ... of water? How is this calculated? ... The molecular weight of water is 18 g/mole.

Answer 2

Answer:

Here is ur answer.......

Explanation:

Given, weight of water = 180 g a) Number of molecules present in water = (given mass / Molar mass) * Avogadro number = (180 / 18) * 6.023*10 23 = 6.023*10 4 molecules
