What is a 5% solution?
4% w / v solution means 4 grams of solute is dissolved in 100 ml of solution.
5% v / v solution means 5 ml of solute is dissolved 100 ml of solution..
How do you make a 1 N NaCl solution?
To make 1 N sodium chloride solution So dissolve 58.5 grams of NaCl in distilled water and makeup to one liter.
How would you prepare a 10% NaCl solution?
To prepare a 10%(w/w) NaCl solution, mass out 10 g NaCl and place it in a 100-mL volumetric flask. Add about 80 mL of water to the flask. Once the NaCl has dissolved, add more water up to the 100-mL mark. If you don’t have a volumetric flask, you can use a 100-mL graduated cylinder, but it won’t be as accurate.
How do you make a 20 percent solution of NaCl?
Thus, 1000 g H2O x 20 g NaCl/80 g H2O = 250 g. Therefore, 250 g of NaCl must be dissolved in 1000 g of water to make a 20 % NaCl solution.
What is 0.5 N NaOH?
One mole of NaOH in one Liter of pure water = 1 N. Since you want 0.5, use 1/2 mole (20.0 grams) of NaOH. … M means Gram Molecular Weight, so 0.5 M means half the gram molecular weight of the chemical. In the case of NaOH the mole. wt. is Na=23, O = 16, H =1, so NaOH = 40.
What is the meaning of 15% solution of NaCl?
It just means that in the aqueous Nacl solution (Nacl dissolved in water) ,each 100 grams of the solution contains 15 grams of Nacl in it .
How do you make a 5% solution of NaCl?
The salt and water together weigh 133 + 7 = 140 ounces. The percent NaCl by mass is therefore (7.0 / 140) x 100 = 5.0 percent NaCl.
How do you make 1 mole of NaCl?
If you dissolve 58.44g of NaCl in a final volume of 1 litre, you have made a 1M NaCl solution. To make a 0.1M NaCl solution, you could weigh 5.844g of NaCl and dissolve it in 1 litre of water; OR 0.5844g of NaCl in 100mL of water (see animation below); OR make a 1:10 dilution of a 1M sample.
How do you make a 150 mM NaCl solution?
It should always indicate the molecular weight. So, for a 1M solution of NaCl you would dissolve 58.44 grams into 1 liter. There are 1000 mM per M so a 150mM solution is 0.15M. Multiply 58.44 by 0.15 and you have the amount of NaCl you need to make one liter of a 150mM solution.
