What would you need to do to calculate the molality of 10 g of NaCl in 2kg of water?
58,49 g NaCl---------------------1 N10 g---------------------------------xx= 10/58,49=0,171 N58,49 is the molar mass of NaCl (for the foemula unit).Molality= 0,171/2=0,085
How do you calculate 100 ml of 0.9 percent NaCL?
To prepare a 0.9% solution take 0.9grams NaCl and dilute with 100mls of water.
The concertration of a water solution of NaCl is 2.48m and it contains 806 g of water How much NaCl is in the solution?
117 grams of NaCl
What are the chemical or physical differences between KCl plus NaBr solution and KBr plus NaCl solution of same molar density?
When you flame test the two solutions, any Na solution burns yellow, while any K solution burns violet/purple. So both the KCl and the KBr will burn purple, while both NaBr and NaCl will burn yellow.
What is the molarity of a solution containing 117 grams of sodium chloride in enough water to make a 40.0 L solution?
[117(g NaCl) / 58.5(g NaCl/mol NaCl)] / 40.0(L solution) = [117/58.5]/40.0 = 2.00(mol NaCl) / 40.0(L) = 0.0500 mol NaCl / L solution = 0.0500 M
A solution of nacl and water has a molality of 4.5m?
The concentration of NaCl is 263 g/L
What is the molality of a solution composed of 20.2 g NaCl dissolved in 685 g of water?
The answer is 0,505.
What is the molality of a solution in which 3.0 moles of NaCl is dissolved in 1.5 Kg of water?
2mol/kg
How to calculate NaCl density?
The density can be measured experimentally.
What would you need to do to calculate the molality of 10 g of NaCl in 2kg of water?
58,49 g NaCl---------------------1 N10 g---------------------------------xx= 10/58,49=0,171 N58,49 is the molar mass of NaCl (for the foemula unit).Molality= 0,171/2=0,085

What would you need to do to calculate the molality of 0.2 kilogram of NaCl in 3 kilogram of water?
convert the .2 kg of NaCl to moles of NaCl.
What is the molality of a solution that has 70g of NaCl dissolved in 300g of water?
Molality(m)= moles of solute divided by kilograms(kg) of solvent you need to find the moles of NaCl by using a conversion factor 70g NaCl = 1mol divided by 58.44g NaCl =1.20mol then you need to convert 300g of water which is the solvent to kilograms by moving the decimal over 3 units to the left which makes .300 kg of solvent Molality= 1.20mol divided by .300kg Molality=4.00
What mass of water is needed to dissolve 292.5g of NaCl to produce 0.25 m aqueous solution?
m (molality)=moles of solute/kg of solvent To calculate moles of solute you convert 292.5 g of NaCl to moles of NaCl. So (292.5gNaCl)(1mole NaCl / 58.4gNaCl)= 5.0085 moles NaCl Now plug and chug. 0.25m=5.0085moles NaCl / x x=5.0085 moles NaCl /.25m x=20kg

Convert the 200 mol of water to kilograms of water.
What would you need to do to calculate the molality of 10 mol NaCl in 200 mol of water?
Convert the 200 mol of water to kilograms of water.
