The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles.

As long as the gas is ideal, 1 mole = 22.4L. You can double check this with our numbers.

2 moles (or 2×18=36 g) of water gives one mole of oxygen.

This means that 1 mole of water weighs 18 grams. Therefore x = (6.5x1)/18 = 0.361 moles. We have 0.361 moles, so: 0.361 x 6.022141 x 10 = 2.174 x 10 molecules.

There are 6.022×1023 molecules in a mole. There are 18.01528 grams of water per mole of water. These can be figured out using the concept of moles and molecular weight.

At STP 1 mole of an ideal gas = 22.4 liters. Assuming that water vapor behaves as an ideal gas, then... 0.08929 moles H2O x 6.02x1023 molecules/mol = 5.4x1022 molecules = 5x1022 molecules (1 sig. fig.)

1 mole of water requires 1 mole of hydrogen (H2) and 0.5 moles of oxygen (O2). This requires 100/18 moles of hydrogen. As the molar mass of hydrogen is 2, it requires 200/18 = 100/9 g of hydrogen. It requires 100/9 g of hydrogen gas and 800/9 g of oxygen gas to make 100 g of water.

( 1/4 of a mole) x (6.02 x 1023 atoms/mole) = approximately 1.5 x 1023 atoms. If you have a compound like H2O, then: one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

and how many molecules are in 50 liters? 5 moles = 22.4*5 = 112 liters;We need to know how many moles are in 50 liters:50/22.4 = 2.23 moles; 2.23 moles * 6.022*1023 mol-1 = 13.44 * 1023 molecules.

The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

So number of moles of water in 50 mg or 0.05 g of water is equal to (1/18) * 0.05 i.e, 2.78 * 10^-3 mol. (2.78 * 10^-3) * (6.022 * 10^23) = 1.67 * 10^21 numbers of water molecule.

In this case, a density of `1.00 g/mL tells you that every milliliter of water has a mass of 1.00 g . Finally, the relationship between number of moles and number of molecules is given by Avogadro's number, which tells you that every mole of a substance contains exactly 6.022⋅2023 molecules of that substance.

It contains Avogadro's number of molecules (6x 10^23). Thus 1 litre of water contains 1 / 18 x 1000 x 6 x 1^23 molecules (assume you can do the maths…)

The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*1023 * 55.556 = 3.346*1025 molecules.

Mass of 1 Mole of Water How much water is that to most people? Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms.

Popular Answers (1) of moles of solute / 1 liter . * one moles of sodium hydroxide = 40 gm of sodium hydroxide. so we can said ; if want prepare 1 molar NaOH solution then we need 40 gm NaOH dissolve in one liter of water so it became one 1 molar NaOH solution.

Well 1 mole of water is 2 moles of hydrogen + 1 mole of oxygen - that is; 1.008 x 2, + 16, which is 18.016 grams. Multiply that by the number of moles - 5, so that's 90.08 grams, or about 90mL. There are 90 grams in 5 moles of water.
