How many moles are in chloroform
WebNaCl = 1.05 * 2 = 2.10 moles; You now know the number of moles of each substance needed in a theoretical perfect reaction. If you want to know the number of grams needed of each substance, you can multiply by the molar mass of each substance: NaOH = 2.10 mol * 39.997 g/mol = 83.9937g; Mg(OH)2 = 1.05 mol * 58.319 g/mol = 61.23495g Web25 dec. 2014 · msolute = 15.0% ⋅ 250g 100% = 37.5g sucrose. So, knowing sucrose's molar mass - 246 g/mol, you'd get the number of moles. nsucrose = m molar.mass = 37.5g 246 g mol = 0.152 moles. If you're dealing with molarity, the number of moles of a solute can be determined by. n = C ⋅ V solution - with the volume and/or the molarity usually given.
