How many moles are in 45g of nitrogen?
1.609 moles in 45 g of N2.
How many moles are in 7 grams of nitrogen?
Explanation: So 7 gram of nitrogen molecule is 7/28=0.25 gm-mole.
What is the mole of nitrogen?
The mass of one mole (molar mass) of nitrogen gas (N2) is 28.0 g/mol .
How many moles are in nitrogen?
14.01 g N = 1 mol N atoms = 6.022⋅1023 N atoms
So all we have to do now is use the correct units, which would be grams per mole, or g/mol. This makes sense because there are about 14.01 grams of nitrogen for every 1 mol of nitrogen, using our ratios above.
What is the moles of oxygen?
Moles of a Substance and the Molecular Weight
The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.
How many moles are in 50g of Caco3?
100g Caco3=1mole.. , 50g of caco3=1÷100×50=0.5 mol..
What is the moles of NaOH?
The molar mass of the compound NaOH is 40 g/mol.
