## How many atoms are in a mole of H2SO4?

You can also say one mole of sulfuric acid has **2 moles of hydrogen atoms**, 1 mol of sulphur atoms, and 4 moles of oxygen atoms.

## How many moles of oxygen atoms are there in 5 mol H2SO4?

Or. 5 mole of H2SO4 contains **20 atoms** of O.

## How many atoms are present in 2 mole of H2SO4?

Answer. Explanation: One sulfuric (H2SO4) molecule has **2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms**. You can also say one mole of sulfuric acid has two moles of hydrogen atoms, 1 mole of sulfur atoms, and 4 moles of oxygen atoms.

## How many moles of Sulphur are present in 5 moles of H2SO4?

The molar mass of hydrogen is 1 ; Molar mass of sulphur (S) is 32 ; Molar mass of oxygen (O) is 16 . Thus, Molar mass of sulphuric acid i.e. H2SO4 is 98. Therefore, 98g for 1 mole, Hence for 5 moles 5×98=**490g** .

## How do you calculate the number of atoms?

To calculate the number of atoms in a sample, **divide its weight in grams by the amu atomic mass from the periodic table**, then multiply the result by Avogadro’s number: 6.02 x 10^23.

## Which has the highest number of atoms?

**4 g of hydrogen contains the largest number of atoms.**

- (A) 4 g of hydrogen (molar mass 2) corresponds to 2 moles of molecules or 4N number of atoms where N is the Avogadro’s number (6. …
- (B) 16 g of oxygen (molar mass 32) corresponds to 0.5 moles of molecules or N number of atoms where N is the Avogadro’s number (6.

## How many atoms of oxygen is present in 0.5 moles of oxygen?

⇒3.011×1023 number of molecules are present in 0.5moles of oxygen molecules. There are **two oxygen atoms** in a single oxygen molecule and this number of atoms is multiplied with the number of molecules. ⇒na=6.023×1023, hence the number of atoms present in 16g of oxygen molecule is 6.023×1023.

## How do we convert from grams to moles?

**Divide the number of grams of the compound**, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).

## How many oxygen atoms are there in 0.5 mol of co2?

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

## How many total atoms are in HNO3?

Answer Expert Verified

Hey! We know that, composition of HNO3 is Hydrogen, Nitrogen and oxygen. Total number of atoms = 3+1+1=**5 atoms** are present in 1 molecule of HNO3.

## 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 formula weight of H2SO4 s 32?

Sulfuric acid’s molar mass is **98.08 g/mol** .
