What is the molar mass of 6H2O?

Answer 1

That depends on other things, like temperature and pressure.

If you know the molar volume (at the specific temperature and pressure), you can calculate it using that.

If you don't, you can use the molar mass (independent of volume and pressure) and the density (which has to be for the specific volume and pressure), which are more commonly listed than the molar volume.

6.6*10^23 molecules = 1.096 moles (use Avogadro) = 19,73 grams (molar mass: 18) = 19,73 mL (density: 1 g/mL)

Answer 2

Avogadro's Number, defined as the number of molecules in one gram molecular mass, is about 6.022 X 1023. Therefore, 6.02 X 1022 molecules of anything, including the water molecules to which the question is directed, constitutes 0.100 mole, to the justified number of significant digits.

Answer 3

6.02x1023 molecules is the same as one mole. One mole of water has 18 grams in it. (H = 1g, O = 16g).

Answer 4

6.9 grams H2O (1 mole H2O/18.016 grams)(6.022 X 10^23/1 mole H2O)

= 2.3 X 10^23 molecules of water

Answer 5

number of moles = wt/M.Wt

Wt = 6.6 gm

M.wt = 18

no. of moles = 6.6/18 = 0.37

so. no. of molecules = 0.37 x 6.023x1023

Answer 6

The Avogadro number is equal to the number of particles in ONE mole of any material
