The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17

The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18

This means that one mole of NH3 weigh less than one mole of H2O

How many grams of H2O do you need to weigh out to have 1 mole of H2O?

To have 1 mole of H2O, you would need to weigh out approximately 18 grams of water (H2O). This is because 1 mole of water molecules (H2O) has a molar mass of about 18 grams/mol (2 grams/mol for hydrogen x 2 atoms + 16 grams/mol for oxygen).


How many grams are in one mole of water using 4 significant figures?

The molar mass of water is approximately 18.02 g/mol. Therefore, one mole of water would weigh approximately 18.02 grams, considering 4 significant figures.


How many grams of H2O are necessary to weigh out 1 mole of H2O?

The molar mass of water (H2O) is approximately 18 grams/mol. Therefore, you would need 18 grams of water to weigh out 1 mole of water.


How many molecules of H2O equals 1 mole of H2O?

In 1 mole of water (H2O), there are approximately 6.022 x 10^23 molecules of H2O.


What is the mass of 2 mole of h2o?

Which weighs more a mole of water or a mole of methane?

It would be a mole of water because you find the molar mass of each compound, finding water is 18.016 g/mol and methane is 16.042 g/mol. Why? water= H2O H 2 x 1.008 O 1 x 16.000 18.016 g/mol methane= CH4 C 1 x 12.010 H 4 x 1.008 16.042 g/mol


How many grams are there in 1.57 moles of water?

1 mole H2O = 18.015g H2O 1.57mol H2O x 18.015g H2O/1mol H2O = 28.3g H2O


Calculate the number of moles of H atoms in 11.5mol H2O?

Since 1 molecule of H2O contains 2 atoms of hydrogen, 11.5 mol of H2O contains 11.5 mol x 2 = 23 mol of hydrogen atoms.


How many mole h2o have in this reaction caco3 plus 2hcl---cacl2 co2 h2o?

In the reaction provided, the balanced equation is: CaCO3 + 2 HCl -> CaCl2 + CO2 + H2O. One mole of CaCO3 reacts with 2 moles of HCl to produce 1 mole of H2O.

Does a mole of water weigh less than a mole of sugar?

No, a mole of water (H2O) and a mole of sugar (C12H22O11) both contain Avogadro's number of molecules, which is approximately 6.022 x 10^23. Therefore, they have the same number of particles and weigh the same, which is about 18 grams for water and about 342 grams for sugar.


How many oxygen atoms are in 0.87 g of water?

0.87 grams water (1 mole H2O/18.016 grams)(1 mole O/1 mole H2O)(6.022 X 1023/1 mole O) = 2.9 X 1022 atoms of oxygen --------------------------------------
