The mass of 0.5 moles of is 49 u.

## What is the mass of 0.5 moles of H2SO4?

(d) Write the names of elements present. (a) Calculate the mass of 0.5 mole of sulphuric acid. Atomic mass (H = 1 u, S = 32 u, O = 16 u). (b) Find the number of atoms in 12 g of carbon.

## What is 0.5 mole mass?

Mass of 0.5 mole of water is 9g.

## What is the mass of 0.25 mole of H2SO4?

0.25 moles of H2SO4 would therefore have a mass of a quarter of 98.08, or 24.52 grams.

## How many moles of O atoms are there in 0.5 mol of H2SO4?

In H2SO4 there are four oxygen atoms. So, for every mole of H2SO4 there are 4 moles of ‘O’. In half a mole of H2SO4 there will be 2 moles of ‘O’.

## How many moles of Sulphur are in H2SO4?

One mole of sulfuric acid consists of one mole of sulphur.

This is because in the molecule of sulfuric acid there is only one atom of sulphur that is present. As a result of this since in case of one mole of sulfuric acid there should be only one 1 mole of sulphur.

## What is the molar mass of H2SO4?

-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 of 0.2 mole of water molecules?

The mass of 1mole of water =18gms. Than, the mass of 0.2moles of water=x. Now x=18×0.2=3.6gms.

## What is the total mass of 3.5 moles of water?

The mass of water is 3.5 moles*18g/mole=63g.

## How many moles are present in 24.5 grams of h2so4?

Answer: The number of moles of will be 0.25 moles.

## How many grams of O is present in 50g of CaCO3?

Calculate the number of oxygen atoms and its mass in 50 g of CaCO3. Solution — Molecular mass of CaCO3= 40+12+3×16 = 100 No. mole of CaCO3 = 50g/100g = 0.5 0.5 mole of CaCO3 contains 1.5 moles of oxygen atoms No. of oxygen atoms = 1.5 × 6.022×1023 = 9.033×1023 atoms Mass of Oxygen atoms = 1.5 × 16 = 24 g.

## How many grams are in one mole of h2so4?

The molar mass of sulfuric acid is 98.0795 g/mol . This means that every mole of sulfuric acid has a mass of 98.0795 g .

## What is the mass of O in one mole of H2SO4?

Answer and Explanation: Therefore, 7.35 moles of oxygens are present in the 2.45 moles of carbonic acid.

## How many oxygen atoms are there in 4.9 g of H2SO4?

4995 moles. Multiply this by 6.022 x 10^23 to get 3.008 x 10^23 molecules of H2SO4 in 49 g. If you multiply this by 4 (there are 4 oxygen atoms in each molecule) you get 1.203 x 10^24 atoms of oxygen.
