How many molecules are there in 12 grams of ice?

Answer 1

Weigh the ice cube (Let's say it weighs 36 grams, about an ounce)

The weight of 1 mole of water is 18 grams

1 mole of anything contains 6.022 x 1023 molecules

In our example:

36 grams of water contains 36/18=2 moles of water

2 moles of water contains 2x 6.022 x 1023 = 12.044 x 1023 molecules

Answer 2

To find the number of molecules in 12 grams of ice, we first need to convert grams to moles using the molar mass of water (H2O). The molar mass of water is 18 g/mol. So, 12 grams of ice is equal to 12/18 = 0.67 moles. One mole of a substance contains 6.022 x 10^23 molecules, so in 0.67 moles of ice, there are 0.67 x 6.022 x 10^23 = 4.03 x 10^23 molecules.

Answer 3

Ice is H2O, which is 18g/mol. 12g H2O = 12/18 = 0.67mol. Multiply by Avogadro's number to get representative particles: 0.67(6.02x10^23) = 4.03x10^23 molecules.

Answer 4

The molecules in ice are the same as the molecules in water, because ice is water. They are H2O molecules, which have two hydrogen and one oxygen. Water molecules are non-polar.

Answer 5

The molar mass of water is 18 g. 12 g is 0.667 of a mole, so there are 0.667 x the avogadro number of molecules.0.667 x 6.022 x 10^23 = 4.017 x 10 ^ 23 approx.

Answer 6

The number of water molecules is 4,014 760 571 3.10e23.
