molarity (M)=(weight/mol.weight)*(1000/volume of the solution in mL)

Now M = (27/17)*(1000//755)=2.1036 mol/lit

divide 27.0 g by the molar mass of NH3 and then divide that by .755 liters.

27,0g NH3*(1mol NH3/ 17g NH3)= 1,59 moles of NH3
M = moles of solute/ L of solution
M = 1,59/(755mL*(1 L/ 1000 mL)= 2,10 M
