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 .
