First, convert 1.97g of (NH4)2SO4 to mole: 1.97/ molar mass of (NH4)2SO4
Second, multiply the answer by 2. Because there is 2 mole of NH4 in every one mole of (NH4)2SO4
Third, divide that answer by 0.343 L (Remember: M (molarity) = mole/Liter)

u simply go grams to mols of ammonium sulfate and then find out how many of those moles are moles of ammonium (multiply by 2), then u divide that by .343 (liters) to get the molarity (concentration) of NH4+
