How many moles of HCl are needed to completely react with 50.0 mL of 0.250 M NaOH solution? A. 1.25 x 10^-2 moles B. 2.50 x 10^-1 moles C. 1.25 x 10^1 moles Please explain. Thank you!
- Volume of NaOH used = V = 19 mL Molarity of the solution of NaOH = M = 0.200 M Volume of the solution of vinegar = V' = 5.00 mL Assuming the molarity of the solution of vinegar to be M'.
- Mar 29, 2010 · 1 mole OH- needs 1 mole H+ to neutralise it. So since you have 0.0150 moles OH- , you must add 0.0150 moles H+ to neutralise. Therefore there must be 0.0150 moles of H+ in the 250 ml of HCl added....
- Since solutions are used moles must be determined using molarity and volume. e.g. How many grams of NaOH are require to neutralize 37.0 mL of a 0.500 M H 2 SO 4 solution? To relate an amount of NaOH to an amount of H 2 SO 4 a balanced equation must be used. Determine the reaction.
- The molar mass of NaOH, {eq}M_n\ =\ 40\ g/mol {/eq} Let's assume that the mass of NaOH is m and the number of moles is n. Then the molarity of the solution can be given as

If you have dissolved 1 g of NaOH in enough water to make a total of 250 ml of solution, calculate the number of moles of solute present by diving the mass of NaOH by the molecular mass of the compound. The molecular mass of NaOH is 40, so work out 1 ÷ 40 = 0.025. Next, calculate the number of liters of solution present.1) molarity=moles/liter 0.5M = x moles / 0.025L x moles = 0.5 x 0.025 x moles = 0.0125 moles of NaOH 2) Calculate the total mass of NaOH Na=23g O=16g H=1g NaOH= 40g per mole or 1 mole of NaOH is...

Molar mass of NaOH is 39.99711 ± 0.00037 g/mol Compound name is sodium hydroxide Convert between NaOH weight and molesSay if someone asks you to calculate the number of moles in 20 ml of a 1M NaOH solution, I would usually say it is going to be 20 mmol as you do 20 ml/1000 ml/L x 1M = 0.02 moles = 20 mmol.
