## How many moles are in 50 grams of water?

There are 3 moles of O in 50 g.

## How many moles are in 500ml of water?

We started with 20ml of liquid and added another 480ml so the new volume of liquid is 20+480=500 ml. so the number of moles we started with is 0.02×0.25=0.005 moles. We haven’t added any more of the substance so we still have 0.005 moles but this is now dissolved in 500ml of liquid.

## How do I calculate moles?

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.

## How do you convert moles to grams?

In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.

## What is the meaning of one mole?

The mole, symbol mol, is the SI unit of amount of substance. One mole contains exactly 6.022 140 76 × 1023 elementary entities. This number is the fixed numerical value of the Avogadro constant, NA, when expressed in mol−1, and is called the Avogadro number.

## How many grams are in 2 moles of HF?

Explanation: Normally 1 mole of F2 reacts with 1 mole of H2 giving 2 moles of HF (which is 20g). We can say that 1 mole of F2 gives 20 g of HF .

## How many moles are in 30 grams of H3PO4?

## How do you calculate moles of water?

Molar mass of atoms

Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. On adding all the above-obtained values we get, Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

## How many moles of hydrogen will you need?

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.
