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
The density of 3 M solution of NaCl is 1.25 g mL-1 Calculate the molality of the solution?
2.79
What would be observed when NaCl is added to water?
When NaCl is added to water, you would observe that it dissolves quite readily.
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.
What would need to be done to calculate the molarity of 10 g of NaCl in 2 kg of water?
10 g of NaCl in 2 kg of water is 5 g of NaCl in 1 kg of water.The molar mass of NaCl is 39,666 g.5 g is equal to 0,318 molal.

A solution of nacl and water has a molality of 4.5m?
The concentration of NaCl is 263 g/L
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
