What mass of NaCl is required to dissolve 100 g NaCl to prepare a 1.50 m solution?
Remember the moles equations.
moles = mass(g) / Mr = [conc] x vol(mL) / 1000
Hence
mass(g) = [conc] x vol(mL) x Mr / 1000 (be algebraic rearragnement)
conc = 0.05 M
Mr = 23 + 35.5 = 58.5
vol(mL) = mass (g) = 150 g =150 mL (NB THis is the standard for water at STP)
Substituting
mas9g) = 0.05 x 58.5 x 150 / 1000
mass(g) = 0.43875 g ~ 0.44 g

How many grams of NaCl would be required to make 6M solution?
It depends on the final solution Volume you want to prepare. For 100ml of a 6M NaCL solution, you add 35.1g of NaCl to water until you reach 100ml. Dissolve and autoclave for 15 mins.
How do you prepare 1 liter of 100ppm NaCl solution?
To prepare a 1 liter of 100ppm NaCl solution, you would dissolve 0.1 grams of NaCl in 1 liter of water. This concentration is achieved by mixing 0.1 grams of NaCl in 1 liter of water.
How can we prepare 1M solution of NaCl?
You could titrate equal volumes of 1M solution of NaOH and 1M solution of HCl to obtain 1M solution of NaCl.
How do you prepare a solution sodium chloride normality?
Dissolve 39,665 g NaCl in 1 kg water.
How do you prepare a solution 2 percent NaCl wv?
To prepare a 2% NaCl (w/v) solution, you would dissolve 2 grams of NaCl in enough water to make 100 mL of solution. This means you would add 2 grams of NaCl to a flask and then add water until the total volume reaches 100 mL.
How do you prepare a 30 percent NaCl solution?
Oh honey, it's not rocket science. Just measure out 30 grams of table salt and dissolve it in enough water to make 100 grams of solution. Voila, you've got yourself a 30% NaCl solution. Just don't go drinking it thinking it's a margarita, okay?
Why is soap solution is saturated with naci?
The NaCl does not dissolve completely in the soap solution because the solution is saturated, meaning it has reached its maximum capacity to dissolve more NaCl. Any additional NaCl added will not dissolve and will remain as a solid in the solution.
How do you prepare 0.2N Sodium chloride solution?
NaCl is the formula for Sodium Chloride, from that you can work out the gram formula mass. RAM Na = 23 RAM Cl = 35.5 gfm (NaCl) = 58.5g mol-1 assuming that you need 0.1l of NaCl m = 58.5*0.1 = 5.85g So dissolve 5.85g in water for a 0.2 mole solution
Does NaCl solution dissolve oil stains?
No, it is not possible.
How do you prepare a 12 percent NaCl solution?
Dissolve 12 g dried sodium chloride (reagent grade) in 100 mL demineralized water.
How do you prepare a 500mL of 1M of NaCl solutuion?
If you need to make just 100mL, then you need 1 tenth of a liter that is 5M. If you were to make 1L of 5 molar NaCl, you would need 5 times the molar mass of NaCl (58.44g/mol) dissolved in 1L of water. Thus for 1L of a 5M solution you need 5 * 58.44g, or 292.2 grams of NaCl. However, since we only want 100mL, which is 1/10 of a Liter, we also only need 1/10 the amount of NaCl, or 292.2 / 10, which is 29.22g. So, measure out 29.22g NaCl, and dissolve completly in a volume less than 100mL, say 80mL, then bring the final volume up to 100mL. You now have 100mL of a 5M NaCl solution.
How do you prepare approximately 100 ml of 1.0 m NaCl?
To prepare 100 ml of 1.0 M NaCl solution, you would need to dissolve 5.84 g of NaCl in enough water to reach a final volume of 100 ml. Measure out the required amount of NaCl, add it to a beaker, and then add water while stirring until the final volume reaches 100 ml.
