72.0 grams NaCl (1 mole NaCl/58.44 grams) = 1.2 moles of sodium chloride
molecular formula for sodium chloride = NaClIf the mole (n) for NaCl = 5.3 moles, then the mole of sodium (Na) = 5.3 moles as well. 1 to 1 ratio mass = moles X molar mass m = 5.3 x 22.9 = 121.37 grams of sodium in 5.3 moles of sodium chloride
The number of moles is 18.56.
23.3772 grams are there in four tenths moles of sodium chloride
.73 moles
0,40 moles of sodium chloride contain 23,376 g.
As the formula for ammonium carbonate is (NH4)2CO3, there are two moles of ammonium for every mole of ammonium carbonate. Just double the given number.
1.946 moles NaCl (58.44 grams/1 mole NaCl) = 113.7 grams sodium chloride ======================

First find out how many grams in 1 mole:Nitrogen is 14.007 g/mol, Hydrogen is 1.0079 g/mol, and Chlorine is 35.453 g/molThere are 4 Hydrogen, so 14.007 + 4*(1.0079) + 35.453 = 53.4916 g/mol(50 g)/(53.4916 g/mol) = 0.9347 moles
0.26 (mol NH4Cl / L) * 0.858 (L) = 0.2231 = 0.22 mol NH4Cl
Ammonium chloride has the formula of NH4Cl. Thus, in each mole there are 4 moles H, 1 mole N and 1 mole Cl for a total of 6 moles of atoms. Then 6.02x10^23 atoms/mole x 6 moles = 3.6x10^24 atoms.
Number of moles = Weight (in g) / Molecular mass (in g/mol) = 8.718 / 96.09 = 0.0907 moles
