What volume of a 2.10 M NaCl solution is needed for a reaction that requires 200 g of NaCl answer in units of L?
First You have to express the 200 g NaCl as moles of NaCl. The molar mass of NaCl is 58.5 g/mole. Consequently you need 200/58.5 g/(g/mole) = 3.42 moles of NaCl.Having a 2.10 M NaCl solution You need 3.42/2.10 mole/(mole/l) = 1.63 l of the given solution.
What is the mole fraction of ethanol in a solution of 3.00 moles of ethanol and 5.00 moles of water?
0.375
A solution was prepared by dissolving 40.0 g of KCl in 225 g of water. Calculate the mole fraction of KCl in the solution?

How many grams of NaCl molecular weight 58.5 g mole -1 would you dissolve in water to make a 0.5M NaCl solution with 500 ml final volume?
14.625
How do you prepare .9 sodium chloride solution?
You take 1.00 mole NaCl, this is 58.45 grams dry substance NaCl, and add (while dissolving) up to 1.00 L water (so you'll need about 0.95 L -LESS than 1.00 L- of water).
How do you convert mole fraction to volume fraction of liquid?
You need the balanced symbol equation for the reaction. The numbers in front of the formulae show the mole ratios. For example, in the thermal decomposition of calcium carbonate: CaCO3 --> CaO + CO2 The equation is balanced. The mole ratio between CaCO3 and CO2 is 1:1 because there is 1 mole of CaCO3 for every mole of CO2

How would you make a 100ml of a Mole solution of Sodium Chloride?
58 grams of NaCl in cylinder measure water to 100ml
What is the mole concentration of 58.44g of NaCl in 1 L of water?
Molarity = moles of solute/Liters of solutionGet moles NaCl.58.44 grams NaCl (1 mole NaCl/58.44 grams)= 1 mole NaCl------------------Molarity = 1 mole NaCl/1 liter= 1 M NaCl========
What is the mole fraction of ethanol in a solution of 3.00 moles of ethanol and 5.00 moles of water?
0.375
How do you calculate for the mole of a solution?
number of moles is mass divided by molecular mass. the molecular mass of NaCl is 58.44g/mol. therefore you need 58.44g to make one mole
Calculate the mole fraction of HCl in 20 percent aqueous solution?
The mole fraction of HCl in 20 percent aqueous solution is 0.21.
What is the concentration M of a NaCl solution prepared by dissolving 3.8 g of NaCl in sufficient water to give 245 mL of solution?
Get moles NaCl and change 245 ml to 0.245 Liters. 3.8 grams NaCl (1 mole NaCl/58.54 grams) = 0.0650 moles NaCl Molarity = moles of solute/Liters of solution Molarity = 0.0650 moles NaCl/0.245 Liters = 0.27 M NaCl ----------------------
How many mL of a 0.420M NaCl solution should be measured out to provide 1.5g NaCl?
1.5g NaCl x (1 mole / 58.5 g NaCl) x (1000 ml / 0.42 mole) = 61.05 ml
