## What is the mass in grams of one water molecule?

18 g/ mol

Water consists of one oxygen atom and two hydrogen atoms. This means that the mass of a water molecule is 1g + 1g + 16g = 18 g/ mol.

**What is the mass grams of 1.0 mole of water molecules?**

18.02 g.

So, one mole of water (6.022 x 10 23 molecules) has a mass of 18.02 g.

**What is the molecular mass of water in kg?**

So, 1 mole of H2O have 18 gm mass. Also, 1 mole of H2O have 6.023×10^23 molecules. So, mass of 1 molecule of H2O is 18/6.023×10^23 gm = 2.988× 10^-26 Kg.

### What is the mass of 1 mole of water class 11?

The mass of one mole of water atom will be 18g. We know that one mole of a particle will contain Avogadro number of atoms.

**How many Kgmol are in 1 kg of liquid water H2O )?**

The molar mass of H2O is 18.015 g/mol. Converting that to kilograms you get . 018015 kg/mol.

**How do you find the mass of one molecule?**

The molecular mass. of a substance is the sum of the average masses of the atoms in one molecule of a substance. It is calculated by adding together the atomic masses of the elements in the substance, each multiplied by its subscript (written or implied) in the molecular formula.

## How many molecules of water are there in 1 Litre of water the density of water is 10 gram per mL?

So, 1 liter =1000ml=1000g water contains 3.36*10^25 water molecule.

**How many molecules of water are there in 1 Litre of water the density of water is 1.0 gram per mL?**

3. 33×1025.

**What is the approximate mass of one water molecule?**

The molar mass of water is 18.015 g/mol. This was calculated by multiplying the atomic weight of hydrogen (1.008) by two and adding the result to the weight for one oxygen (15.999). Please remember that you need the molar mass first when trying to find the average mass of one molecule. 2) Divide the substance’s molar mass by Avogadro’s Number.

### How do you calculate the mass of water?

Calculate the density by dividing the mass by the volume. Using the equation density = mass/volume, you can determine the density of water. Plug in the values of mass and volume you determined and solve.

**What is the volume of 1 molecule of water?**

The volume of one water molecule is #2.99 × 10^”-23″ “cm”^3#.

**What is the formula mass of water?**

Answer: 1 kilogram. To compute the mass of a volume of water, you used the formula: Mass = Volume * Density. where the density of water is 1,000 kilograms per cubic meter.
