Quick Answer: How many moles are there in 9g of water?

How many moles are there in 9g of H2O?

= 0.5 Moles of H2O .

How many molecules are in 9g of water?

3.01 × 10. 6.022 × 10.

How many moles are in 10g of water?

1 mole of water weighs 18g. 10/18 moles = 10/18 * 6 * 10^23 number of molecules = 3.33 * 10^23 molecules of water. Each molecule of water has 3 atoms, so the total number of atoms in 10g of water is 3*3.33*10^23 = 10^24.

How many moles are in one gram of water?

The average mass of one H2O molecule is 18.02 amu. 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.

How many moles of are there in 1000 g of water?

Now 18g of H20 is equivalent to 1 mole. Hence, 1000g of it would be equal to 1000/18 moles. This comes out be 55.55 moles. Thus 1 kg of water or ice has 55.55 moles of H20.

How many moles is 17g of water?

Hence 17 gm of H2O2 = 1/ 34 ×17 = 1/ 2 = 0.5moles.

How many moles are present in 10 g of H2O?

One mole of any substance weighs about the same as the molecular mass of that substance. Hence, there are [3.34times {10^{23}}] molecules of [{H_2}O] present in a 10 gram sample of [{H_2}O] .

How many H2O molecules are in 10 grams of water?

10 g of H2O cotains =6.022×102318×10 = 3.34×1023 molecules.
