How many atoms are there in hydrogen?
A hydrogen, nitrogen, or oxygen molecule, consists of two identical atoms of each of those respective elements. Therefore, a hydrogen molecule’s mass is 2 amu, oxygen is 32 amu and nitrogen is 28 amu.
How many atoms are in the planet Earth?
133,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
According to the US Department of Energy’s Jefferson Lab, the answer is: 133,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. That answer comes from an estimation of the number of atoms in each of Earth’s elements, like Iron, Oxygen, Silicon, Magnesium, Sulfur … etc.
How many molecules are there in 2h2o2?
If there are two hydrogen peroxide molecules, that means that two water molecules and two oxygen molecules came together. We use moles because it effectively removes the mass dependence in chemical equations. Relevance.
How do you calculate hydrogen atoms?
Explanation: To determine the number of hydrogen atoms, divide the mass of ethanol by its molar mass to get moles of ethanol. Multiply this by six atoms of hydrogen per molecule of ethanol and by Avogadro’s number to get the number of hydrogen atoms.

How many atoms are in a molecule of sodium nitrate?
In one MOLECULE of sodium nitrate (NaNO3) there will be 3 atoms of oxygen. How many moles of NaNO3 are in 230 g of NaNO3? How many moles are in 60.1 grams of of NaNO3? For this you need the atomic (molecular) mass of NaNO3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.
