Milli means one thousandth. So there are 1000 millimoles in a mole. Therefore 56/1000 gives you 0.056 moles.
0.0280 moles
The number of moles is 1,8.
The same number of moles for each.
Determine the number of moles 15.5 g NaOH 15.5 g NaOH x (1 mole NaOH/39.9971 grams NaOH) = 0.388 moles NaOH Molarity = moles NaOH/L solution 0.540 M = 0.388 moles NaOH/L soln L soln = 0.718 L --> A
Need moles sodium hydroxide first.80 grams NaOH (1 mole NaOH/39.998 grams) = 2.000 moles NaOHMolarity = moles of solute/Liters of solutionMolality = 2.000 moles NaOH/1 liter= 2 M NaOH solution===============

Molarity = moles of solute/Liters of solution 3.42 M NaOH = 1.3 moles NaOH/Liters NaOH Liters NaOH = 1.3 moles NaOH/3.42 M NaOH = 0.38 Liters
3.42 moles NaOH (39.998 grams/1 mole NaOH) = 137 grams NaOH

1st Get the balanced equation NaOH + HCl -> NaCl + H2O Find the number of moles in HCl; n = cv n = 0.46x0.61 n = 0.2806 moles the number of moles of HCl and NaOH is the same so 0.2806moles will be needed
moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
8 grams NaOH (1 mole NaOH/39.998 grams) = 0.2 moles NaOH
0.75 moles in 30.0g of NaOH.
