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 )
20 grams of NaOH to moles?
mass divided by molar mass gives moles: 20 g NaOH / 40 g.mol-1 = 0.5 mol NaOH
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 do you convert normal eg 10.0N NaOH to percent concentration?

How many grams of solute in 1.8 L of a 3.5 M NaOH solution?
The mass of NaOH is 352 g.
What is the mass of 3.42 moles of NaOH?
3.42 moles NaOH (39.998 grams/1 mole NaOH) = 137 grams 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 mass of NaOH is in 290 mL of a 1.7 M NaOH solution?
197.2 grams of NaOH is present in 290ml of 1.7 NaoH solution as the formula for Molarity is Mass of solute x 1000/ equivalent mass x volume
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 the aqueous NaOH?
This depends on the mass of NaOH dissolved in 1 L water.
How many moles are there in 9.4 g of NaOH?
Molecular mass of NaOH= 40.0 grams9.40 grams / (40.0 grams) = .235 moles NaOH
What is 83 grams of sodium hydroxide in moles?
For this you need the atomic (molecular) mass of NaOH. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaOH= 40.083.0 grams NaOH / (40.0 grams)= 2.08 moles NaOH
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 grams of solute in 1.8 L of a 3.5 M NaOH solution?
The mass of NaOH is 352 g.
What is the molecular mass of NaOH?
39.997 g mol-1
When weighing out NaOH pellets why does the mass as read on the optical scale of the balance continuously increase?
Because NaOH is a hygroscopic compound and continuously absorbs moisture from air and its mass becomes increased.
