## What is the mass of 0.5 mole?

So, mass of 0.5 mole of water is given as. ⇒m=0.5×18. ⇒m=9g.

## What is the mass of 0.5 mole of h20?

Thus, the mass of 1 mole of water is 18 grams. Now, Mass of 1 mole of water =18 g. So, Mass of 0.5 mole of water =18×0.5g. =9g. Thus, the mass of 0.5 mole of water (H2O) is 9 grams.

## What is the mass of 0.5 mole of c12 gas?

Calculate the mass of 0.5 mole of N atoms. Given: Number of moles = 0.5 Atomic mass of N = 14 u Molar mass of N = 14g/mol To calculate the mass, apply the formula: We can write: Page 6 Mass(m) = Number of moles (n) × Molar mass (M) Mass = 0.5 mol × 14g/mol Mass = 7g Thus, the mass of 0.5 mole of Natoms is 7g.

## What is the mass of 0.2 mole of water?

What is the mass of : (a) 0.2 mole of oxygen atoms? (b) 0.5 mole of water molecules? Ans. ∴ 0.2 mole of oxygen atoms = 16 × 0.2 = 3.2 g (b) 1 mole of water molecules = 18 g ∴ 0.5 mole of water molecules = 18 × 0.5 = 9 g 10. Calculate the number of molecules of sulphur (S8) present in 16 g of solid sulphur.

## What is the mass in gram of 5 moles of water?

5 mole of water =0. 5×18 =9gm. Was this answer helpful?

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

Gram mole is same as mole. 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 0.5 moles of water?

so, mass of 0.5 mole of H2O=18*0.5

=9grams.

## What is the mass of 0.2 mole of oxygen?

-Therefore, the mass of 0.2 moles of oxygen atom is 3.2 grams and the mass of 0.5 moles of a water molecule is 9.0 grams.

## What is the mass in grams of 5 moles of Fe2O3?

What is the mass of 5 moles of Fe2O3? 1st find Molar Mass of fe 02 Fe = (55.85)/2) = 111.7g Total = 159.78] Smol l 159.79 rezoz – 799 Garans Poon BO=(16Y3) – 489 Timol = 798.5 3. Find the number of moles of argon in 452 g of argon.

## What is the weight of 2.0 gram mole of CO2?

The weight of CO2 is 44 grams per mole (1 x 12 grams/mole for the carbon and 2 x 16 grams/mole for the oxygen atoms). Burning one mole of octane (114 grams), therefore, would produce eight moles of CO2, with a weight of 352 grams (8 x 44).

## How do you find the mass of 0.5 moles of CO2?

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.
