Determine the mass in grams of NH3 (Mm = 17.03 g / mol) that must be dissolved in 475 g H2O to obtain a 0.250 m solution
Added by Christopher A.
Step 1
Given: Molar mass of NH3 (Mm) = 17.03 g/mol Molarity (m) = 0.250 mol/L Volume of solution (V) = 475 g H2O Number of moles of NH3 = Molarity * Volume Number of moles of NH3 = 0.250 mol/L * 475 g / 17.03 g/mol Number of moles of NH3 = 13.22 mol Show more…
