How many molecules are present in 10g of H2O?

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

How many molecules are present in a 9g of water B 17g of ammonia?

b) 17g of ammonium. 9 g of water = 0.5 moles = 6.023 x 1023 / 2 = 3.011 x 1023 molecules. Thus 17g of ammonia will have 6.023 x 1023 molecules.

How many grams of water is in h20?

18.02 grams
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 molecules of H2O are present in 3.45 g H2O?

3.50⋅mol×6.022×1023⋅mol−1≅21×1023 individual water molecules.

How many molecules of water are in 180g of H2O?

X =180/18 =10 moles.

How many molecules are there in 10g of H2O?

1 mole contains 6.022×10 23 molecules Thus no. of molecules in 10 gof H 2 O is 1810 ×6.022×10 23 molecules =3.34×10 23 molecules of H 2

How many molecules of water are in 9 grams of water?

Water has 18 grams per mole so 9 grams is 0.5 moles of water. There are 6.022* 10^23 molecules in a mole. Each water molecule contains *one* oxygen and *two* hydrogens. SO! We have in 9 grams of water.

How many moles are there in 09 grams of H2O?

18 gram og H2O is equal to 01 mole. Now if we take 09 gram of H2O it ll be half mole of it. 8 clever moves when you have $1,000 in the bank. We’ve put together a list of 8 money apps to get you on the path towards a bright financial future.

How many hydrogen atoms are in a mole of water?

So there’s two hydrogen atoms and one oxygen atom in a molecule of water. Since oxygen has an atomic weight of 16 and hydrogen one of 1, the atomic weight of water is 16+2*1=18. Now. From the way avogadro’s number is defined, we know that one mole of water, that is 6.022*10^23 molecules of water, weigh exactly 18 grams.
