Your question: How many moles are in 125g of water?

How much moles are in water?

The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol. Notice that the molar mass and the formula mass are numerically the same.

How many moles are in 180g of water?

Moles of water =18018=10 mole.

How many moles are in 200g of water?

that’s 18 grams! Since the density of water is 1, the volume of water and the mass of water are the same. Example: If someone can fit 200 gram (ml) of water into their mouth, how many moles of water is this: 200 grams of water x 1 mole of H2O = 11 moles 18grams 4.

How do you find moles of water?

To do this, we divide mass of water by the molar mass of water to get moles of water. Remember that the units for molar mass are g/mol. When we divide mass (in g) by molar mass (g/mol), grams will cancel out and we will be left with moles.

What is the mole of 20g of water?

so 20 g of water = 1.11 mol of water

Convert into mole.
