How many moles are in 8g of NaOH?
The answer is 39.99711.
How many grams are in a mole of NaOH?
The molar mass of the compound NaOH is 40 g/mol.
How many moles are in 2 grams of NaOH?
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles NaOH, or 39.99711 grams.
What is the mole of NaOH?
Their respective atomic weights are: Na – 23,0 – 16 and H – 1, so the molecular weight, is 23 + 16 + I = 40. Thus 40 grams of NaOH equals one mole of NaOH, and a 1 molar solution of NaOH will contain 40 grams of NaOH chemical.
How many moles are in 10 grams of NaOH?
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide. The SI base unit for amount of substance is the mole.
How many moles is 40g of NaOH?
Now take 120 grams NaOh and multiply this by 1 mol NaOH/ 40 grams NaOH. You can cancel out the grams and you have moles left. Now you do 120 x 1 / 40 and you get 3 moles of NaOH!
How do I calculate moles?
- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
How many moles are in 50 grams of water?
The answer is 18.01528. We assume you are converting between grams Water and mole. You can view more details on each measurement unit: molecular weight of Water or mol The molecular formula for Water is H2O. The SI base unit for amount of substance is the mole.
How many moles are in 5g of NaOH?
Moles = mass / molar mass
So, 0.125 moles are present in 5g of NaOH.
What is the mass of 0.75 moles of NaOH?
There are 0.25 L of solution (250mL⋅1L1000mL) , so there are 0.25L⋅3.0mol/L=0.75mol of NaOH. The molar mass of NaOH is 40.0 g/mol, so there are 0.75mol⋅40.0g/mol=30g of NaOH, 30. g with the right number of significant figures.
How many grams are in 2 moles of MgCl2?
For example magensium chloride has the formula unit MgCl2 , i..e., for every magnesium cation there are two chloride anions in the crystal. Or, we would say that the formula weight of MgCl2 = 95.211 g/mol (i.e., 95.211 g of magnesium chloride has a mole of magnesium cations and 2 moles of chloride anions.
How many moles is 17.6 grams of NaOH?
Answer: The answer is 39.99711.
How many moles are in 1l of NaOH?
molarity = no. of moles of solute / 1 liter . * one moles of sodium hydroxide = 40 gm of sodium hydroxide. so we can said ; if want prepare 1 molar NaOH solution then we need 40 gm NaOH dissolve in one liter of water so it became one 1 molar NaOH solution.
How many moles are in 4g of sodium hydroxide?
Answer. =0.10 (approx.)
