How many moles of HCl are represented by 1.0 x 1019 HCl molecules?

Answer 1

The number of Avogadro states that 1 mole equals 6.02214179*10^23 mole.

So if you have 1*10^19 HCl molecules, you have:

1*10^19 / 6.02214179*10^23 = 1.660538783*10^-5 mole of HCl.

Which equals 0.0166053878 milimole.

Answer 2

Use the following:

1.0 mole HCl = 36.46 g and 1.0 mole = 6.022*1023 molecules,

to calculate:

1 molecule = 36.46(g/mol) / 6.022*1023(molecules/mol) = 6.054*10-23 gram

Answer 3

Add the atomic weights of each atom:

2 atoms of hydrogen at 1.008 each

1 atom of carbon at 12.011

3 atoms of oxygen at 15.999 each

62.024 total.

Answer 4

1,0 x 1019 HCl molecules is equal to the 1,66.10e-5 moles.

Answer 5

1.0 x 10^19 HCl molecules represent 1.66 x 10^-4 moles of HCl. This can be calculated by dividing the number of molecules by Avogadro's number (6.022 x 10^23 molecules/mol).

Answer 6

36.44 grams in one mole HCl
