How many grams of solid NaOH should I use to make 25 mL of a solution that is 5 M in NaOH? 5 grams 10. Suppose that I take 13 uL of the solution in #9, and add it to a microtiter well to which I add other solutions that bring the final volume to 250 uL. If none of the other solutions include sodium, what's the number of grams of sodium in the final solution? 2.6 mg (0.0026 grams) A... 0.250 40 g NaOH mol NaOH mol NaOH gNaOH = Step #2 – Divide moles of solute by liters of solution: 0.250 0.125 2 mol NaOH. M NaOH L = 1) 20 grams of NaOH is dissolved in enough water to make 1 liter of solution . 2) 45 grams of glucose, C 6H 12O 6 is dissolved in enough water to make 0.500 liters of solution . 3) 116 grams of KF is dissolved in enough water to make 4 L of solution . 4) 63
How many grams of NaOH are needed to make 100 mL of a 0.5
How many g of copper(II) hydroxide are needed to prepare 150 ml of 0.05 M solution? 0.7g Cu(OH)₂ If 4.0 g NaOH are used to make 500. mL of NaOH solution, what is the molarity (M) of the solution? how to make ear headbands One mole of NaOH weighs 23(Na)+16(O)+1(H)=40 g A 0.05 M NaOH is then 2 g NaOH/L. So dissolve 2 g NaOH in 500 ml water let it cool down to room temperature and fill it up t … o one liter.
