How many atoms are there in 1 mole of HNO3?
Note the amounts of atoms of all the component in HNO3, which are 1 atom of Hydrogen, 1 atom of Nitrogen and 3 atoms of Oxygen. Multiply each of the atomic weights by the amount of atoms of each element contained in the compound. Add up the results to obtain the molar mass: 1 + 14 + (16 x 3) = 63 gr/mole.
How many atoms of each kind are present in 1 molecule of HNO3?
5 Atoms are present in 1 molecule of HNO3. 3 atoms of oxygen.
How many atoms are in 2 moles of HNO3?
Explanation: In 2 moles of nitric acid there are 2 moles of hydrogen atoms, 6 moles of oxygen atoms, and 2 moles of nitrogen atoms.
What is the number of atoms in 1 mole?
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).
How many total atoms are present 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 molecules of HNO3 are present?
Nitric acid is composed of HNO3 molecules.
What is the ratio of molecules in 1 mole of NH3 and 1 mole of HNO3?
Answer: The ratio of molecules in 1 mole of NH3 and 1 mole of HNO3 is 1:1. Explanation: Mole is a SI unit which we use to measure the amount of the chemical compounds.
How many atoms are present in a molecule?
Molecule: group of two or more atoms held together by chemical bonds. So, minimum 2 atoms are required to form a molecule.
How many atoms are there in caco3?
Calcium carbonate is a molecule that contains one atom of calcium, one atom of carbon, and three atoms of oxygen.
What is correct for 10gm of caco3?
100 grams of Calcium Carbonate contains 40 grams of Calcium, 12 grams of Carbon and 48 grams of oxygen. … Therefore, 10 grams of Calcium Carbonate contains 0.3 g-atom of Oxygen, 0.1 g-atom of Carbon, and 4 grams of calcium.
How many moles of oxygen atoms are present in 2 mol HNO3?
NITRIC ACID IS HNO3 FROM THE MOLECULAR FROM WE CAN EASILY SEE THAT ONE MOLE OF HNO3 CONTAINS 3 MOLES OF O2 SO IF THERE IS 2 MOLES PRESNT IN THE SOLUTION THERE WILL 2*3 MOLES OF O2 WHICH I EQUAL TO 6.
