How many grams in 30 ounces of water?

Answer 1

The Molecular mass of Water (H2O) is 18.0153 gmol-1

If the number of moles=mass/molecular mass

Then in 30 grams of water;

30/18.0153 = 1.665251203 moles.

This corresponds to 1.66...moles x NA = 1.002838 x 1024 Molecules of water.

One molecule of H2O has 10 electrons

Therefore 30g of water must contain 10 x (1.002838 x 1024) =

1.002838 x 1025 electrons

Answer 2

30 (g H2O) divided by 18 (g H2O)/(mol H2O) is 1.7 (mol H2O)

Answer 3

1 gram water (1 mole water/18.016 grams)(6.022 X 1023/1 mole water)

= 3.34 X 1022 atoms of water

======================Now,

water is H2O, two atoms of hydrogen and one atom of oxygen

2H = 2 electrons

O = 8 electrons

================add

10 electrons total, so

10 electrons * 3.34 X 1022 atoms

= 3.34 X 1023 electrons is 1 gram water

=============================

Answer 4

30 g Pb x 1 mol Pb/207.2 g Pb x 6.02x10^23 atoms/mole = 8.7x10^22 atoms

Answer 5

The number of atoms is in 30 grams of lead is 0872.10e23.

Answer 6

There are approximately 850 grams in 30 ounces of water.

Answer 7

That is 850.486 grams
