define weight percent and volume percent.
Answers
Explanation:
Weight Percentage :
wt% means weight percent which is sometimes written as w/w i.e. [ weight of solute/ weight of solvent*100 = percent of solute in the solution].
Formula is :
To determine the weight per cent of a solution, divide the mass of solute by mass of the solution (solute and solvent together) and multiply by 100 to obtain per cent
.Example: %w/w concentrations
you were making 100 g of your product and add 50 ml of the oil during manufacture, this will be 50 x 0.9 g/ml = 45 g. Therefore, in 100g of your product's solution, 45 g of this will be your oil, meaning that it has a %w/w of 45.000.
Volume Percentage :
Volume/volume percentage (v/v percent) is a measure of the concentration of a substance in a solution. It is expressed as the ratio of the volume of the solute to the total volume of the solution multiplied by 100.
Formula is:
Volume Percent=Volume of SoluteVolume of Solution×100% Examples: Volume/Volume Percentage
Wine has a typical alcohol content (v/v percent) of 12 percent. This means that there is 12 mL of ethanol in every 100 mL of wine
