(Atomic masses : H = 1 u, O = 16 u) Thus, the mass of 1 mole of water is 18 grams. Thus, the mass of 0.5 mole of water (H2O) is 9 grams.

## What is the 0.5 moles of water?

Mass of 0.5 mole of water is 9g.

## How many molecules is 0.5 moles H2O?

There are ~3*10^23 molecules of H2O in 0.5 mole.

## How do you calculate 0.5 moles?

To find the mass of a certain number of moles of a substance, we multiply the number of moles of the substance by its molar mass.

- Carbon dioxide (CO2) has a molar mass of 44.01 g/mol . Here, there are 0.5 mol of the molecule. So, the mass of this sample is:
- m=44.01 gmol ⋅0.5mol.
- ≈22 g.

## What is the mass of 0.1 mole of water?

Molecular formula of water is H2O. So, adding the two we get the weight of one mole of water, which is 18g.

## What is the mass of O 5 mole of water molecules?

Answer: Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of 90.05 g.

## What is the mass of 0.5 mole water and ammonia?

Thus, the mass of 0.5 mole of water (H2O) is 9 grams.

## How many hydrogen atom are there in 0.5 mole of water?

There are 6. 022×1023 H20 molecules in it. (Atomic mass H=1,O=16,Cl=35. 5,N=14)

## How many oxygen atoms are there in 0.5 mole of water?

So 0.5 mol of Oxygen has 3.011*10^23 atoms.

## How many atoms are there in 0.5 moles of hydrogen?

There are 4 H atoms per molecule. Therefore, 0.5 moles contains 12 x 10^23 atoms of H.

## What do you mean by 0.5 mole of CO2?

Because mass of carbon is 12 and mass of oxygen is 16. So mass of one mole of CO2=12+ (16×2)=44. So mass of half a mole of carbon dioxide is 1/2×44=22g.

## What is the mass of 0.5 mole of silver?

The mass of 0.5 mole of silver is equal to 54g.

## How many molecules are in 0.5 moles of a compound?

So, one mole of a substance contains exactly the Avogadro number (N) of particles. Where NS is the number of molecules in the substance. It is given to us that there are 0.5 moles of glucose present. Hence, there are 3.011×1023 molecules in 0.5moles of glucose.

## How do you find the mass of a 0.1 mole?

Mass of 0.1 mole of CO_{2} will be 44 x 0.1 = 4.4 g.

## How many h2o molecules are in one mole of water?

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.
