according to my teacher but i dont know the formula
280 grams
Need to know how much of the solution you have.
The mass of sodium hypochlorite in 2,5 kg solution is 131,25 g.Sodium chloride is only the product of a decomposition.
137.5 gm
Take 100 grams of 5% solution and do one of the following:Mix 95 g of it with 5 grams of sugar to end up with 100 g of 10% solution, or, when you are short of sugar:Evaporate 50 grams of water from 100 g of the 5% solution to end up with 50 g of 10% solution.
The mass of sugar is 100 g.
23.75 mg of Dextrose is added by intravenous injection of 475 ml of this solution .. wrong!5% WV means 5 grams/100ml ; therefore 23.75 grams/475ml; since there's 1000mg/gramthe number of mg dextrose added by IV injection of 475ml = 23750mg !
You have 100 grams of pure dextrose and 9 grams of pure sodium chloride added to one liter of distilled water. The solution is sterilized and packed in polypropylene or polyethylene bottles.
I hope you don't work in a hospital, and I also hope you have passed 7th grade.But, 5% of a 1 L (1000 g) solution would be 50 grams.
2g?
A. 2 g
We first calculate the amount, in moles, of NaCl that we will need.Amount of NaCl needed = 0.24 x 400/100 = 0.096mol. Mass of NaCl needed = (23.0 + 35.5) x 0.096 = 5.616g So to produce 400ml of 0.24M NaCl solution, accurately add 5.616 grams of NaCl to 400ml of deionised water.
40.8 grams
1L = approx 1Kg therefore 1ml = 1g so 400ml = 400g
Unfortunately sugar is an imprecise term. It is better to specify glucose (usually means dextrose) or sucrose or fructose etc.A 5 percent solution of one of these sugars would contain 5 grams weight dissolved in 100mL of water (or could be another solvent).Read more: What_does_a_5_percent_sugar_solution_mean
