## How many moles are in 1kg?

The idea here is that 1 kg-mole is equal to 103 moles.

## How many water molecules are in 1kg of water?

Figure out how many water molecules there are in 1 kg of water. (Hint: The atomic mass of water is 18D* and Avogadro’s number is ~ 6 x 1023 molecules/mole.) Since 1 kg of water has 1000 g, that corresponds to 1000/18 moles. That would have (103/18) x (6 x 1023) ~ 3 x 1025 molecules of water.

## How many moles are in 1 kg of oxygen?

so,62.5 moles of oxygen have (6.022×10^23×62.5) molecules. Hence 1 kg of oxygen has (376.38×10^23) molecules.

## What is the molarity of 1 kg of water?

= 55.56 M. Thus, the molarity of the water is 55.56 M.

## How many water molecules are in 2 liters of water?

0.08929 moles H2O x 6.02×1023 molecules/mol = 5.4×1022 molecules = 5×1022 molecules (1 sig.

## How many molecules are in a kilogram?

If a molecule weighs X amu, then a mass of it that weighs X grams has 6.022×10^23 molecules in it. This last number is called Avagadro’s number and is familiar to any high school chemistry student. So 1g = 6.022×10^23 amu. Therefore 1 kg = 6.022×10^26 amu.

## How many moles of oxygen will you need for 100 grams of water?

There are 6.25 moles of oxygen in 100g of Water.

## How many moles are in 200g of water?

that’s 18 grams! Since the density of water is 1, the volume of water and the mass of water are the same. Example: If someone can fit 200 gram (ml) of water into their mouth, how many moles of water is this: 200 grams of water x 1 mole of H2O = 11 moles 18grams 4.

## Could you swim in a mole of water?

If you had a mole of water molecules, could you go swimming? The answer is no, it’s not enough water. 1 mole of water molecules is 18.02 grams of water. That’s about 18 mL of water since the density of water is roughly 1 g/mL.
