a solution of sodium nitrate has a concentration of 0.733 M and a density of 1.0392 g/mL
A) write the molarity as a fraction(moles/liters solution)
B) rearrange the molarity equation and solve for volume
C) find the mass of the moles of sodium nitrate
help??
thanks

I dont wanna do the calculations, you do it ( so you can actually try). I'll just say how get the number of mols of KOH... volume (in litres) x molar concentration of KOH then, check the ratio. in the equation-- 2 molecules of KOH is required to react with 1 molecule of H2SO4. so to get the number of mols of H2SO4, just dived the mols of KOH by 2 then just mols of H2SO4/volume (in litres) = molarity of H2SO4 molarity is the same as molar concentration
