20 grams of NaOH to moles?
mass divided by molar mass gives moles: 20 g NaOH / 40 g.mol-1 = 0.5 mol NaOH
Dissolve 2 moles of NaOH in 6 kg of water?
The solution has a molar concentration of 0,33.
What is the total number of moles of solute in 2.0 liters of 3.0 M NaOH?
I believe the molarity is 1. molarity = number of moles / liters of solution molarity = 3 / 3 = 1
How many grams does 2.2 moles of NaOH weigh?
Need total molar mass sodium hydroxide which you can easily get from your periodic table. 2.2 moles NaOH (39.998 grams/1 mole NaOH) = 88 grams in mass ==============
How many moles are in 12.0 g NaOH?
The molar weight of NaOH is approx. 40 g/molSo 12.0 g of NaOH would be approx 12/40 = 0.3 mol NaOH
20 grams of NaOH to moles?
mass divided by molar mass gives moles: 20 g NaOH / 40 g.mol-1 = 0.5 mol NaOH
What is the molarity of 32.0 of NaOH in 450 of NaOH solution?
I assume you mean 32.0 grams of NaOH and 450 milliliters of NaOH. Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters ) get moles of NaOH 32.0 grams NaOH (1 mole NaOH/39.998 grams) = 0.800 moles NaOH Molarity = 0.800 moles NaOH/0.450 liters = 1.78 Molar NaOH
Dissolve 2 moles of NaOH in 6 kg of water?
The solution has a molar concentration of 0,33.
How many moles of NaOH are in 23.3 mL of 0.162 M NaOH?
The number of moles is 0,0038.
What is the total number of moles of solute in 2.0 liters of 3.0 M NaOH?
I believe the molarity is 1. molarity = number of moles / liters of solution molarity = 3 / 3 = 1

How many moles are in 12.0 g NaOH?
The molar weight of NaOH is approx. 40 g/molSo 12.0 g of NaOH would be approx 12/40 = 0.3 mol NaOH
What is the mass of 2.75 moles of sodium hydroxide?
Molar mass of NaOH is 39.998 grams. So, 2.75 mol NaOH (39.998g NaOH/1 mol NaOH) = 109.9945 grams NaOH ( you do the sigi figi )
What is the number of moles of sodium hydroxide NaOH corresponding to 10.84 and times 1023 formula units of NaOH?
The number of moles is 1,8.
How many Moles of NaOH equals the moles of KHP?
The same number of moles for each.
What is the minimum molarity of HCl when titrated with 18.6ml of NaOH?
First of all, it is HCl solution, more properly hydrochloric acid (that is HC l ). It is composed of hydrogen (H) and chlorine (Cl). The answer depends on the volume of the acid and the concentration of the alkali. Here is a sample calculation with some random values for the variables you have not given. If the HCl is neutralized by 25.0 ml of 0.500 M NaOH, then the number of moles of NaOH equals the number of moles of HCl. 25 ml is equal to 0.025 liters, and since molarity is moles per liter we have: Moles of NaOH = 0.0250 Liters * 0.500 moles/liter = 0.0125 moles Moles of NaOH = moles of HCl = 0.0125 moles If there are 0.0125 moles HCl in 45.0 ml (or 0.045 L), then the molarity of the HCl is: 0.0125 moles ÷ 0.0450 L = 0.278 moles/L = 0.278 M HCl
How do you prepare 0.5 N NaOH solution?
There is 0.5 moles of NaOH per litre To calculate 0.5 molar NaOH first know the molecular weight of NaOH i.e 40 now multiply the number of moles of NaOH you have (0.5) found as above. so to find the number of grams of NaOH we needed to start with (0.5) * (40) = 20g So dissolve 20g of NaOH in one litre of the solution to prepare 0.5 molar solution
