How many grams needed from water to prepare 160 grams from potassium acetate 5 percent w?
160 g (solution) - [5/100*160] g (solute) = 152 g (solvent) water
What mass of potassium benzoate trihydrate is needed to prepare one liter of a 0.125 molar solution of potassium benzoate?
From the definition of molar concentration, the required amount of solute for the solution specified is 0.125 moles. The gram formula mass for potassium benzoate trihydrate is 214.26. Therefore, the mass required is 0.125 X 214.26 or about 26.8 grams, to the justified number of significant digits.
A solution has a density of 1.50 grams per milileter at 25.0 degrees Celsius How many grams are needed to obtain 5.00 ml of the solution?
7.5 grams are needed because each milliliter is 1.50 grams, to get 5.00 mls, the calculation would be 5x1.50=7.5.
How many grams of potassium chlorate are needed to make 250.0ml of a 1.550M potassium chlorate?
(1.550M/liter of solution)(122.55 g/mole of KCLO3) = 190.0 g/liter(190.0 g/ 1000 mL) x 250.0 mL = 47.50 g/250.0 mL
If the percentage for a solute is 4 per cent and the mass of the solution is 200 grams what is the mass of the solute in solution?
200 grams of solution will contain 200 x 4% or 200 x 0.04 = 8.0 total grams of solute.
