The answer is 0,4 moles.
978 g calcium contain 24,4 moles.
14,84 g magnesium are equivalent to 0,61 moles.
67,4 g HCl is equivalent to 1,85 moles.
573,28 of g of AgCI is equivalent to 4 moles.
The number of moles is 3,316 (for atomic nitrogen).
0,189 g of N2O equal 0,0043 mol.
[ 217(g) / 44.013(g/mol) ] * 2(molN/molN2O) = 9.86 mol NDivide mass (g) by molar mass (g/mol) to get moles of N2O, this should be multiplied by 2 for the stoechiometric factor of atoms N per molecule N2O.
The answer is 1,52 moles.
Molar mass: 44.013 g/mole 81.0/44.013=1.84 mole N2O Moles of N 1 mole N2O contains 2 atoms N 1.84 mole N2O contain 1.84*2=3.68 mole N atoms
I mole N2O = 44g, so 2.22 mol is 97.68 g.
3,80 g Zn have 0,058 moles.
The formula is: number of moles = g Be/9,012.
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
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. NaNO3=85.0 grams60.1 grams NaNO3 / (85.0 grams) = .707 moles NaNO3
The answer is 0,4 moles.
The answer is 0,364 moles.
