75
25%% rate:= 75/300 * 100%= 0.25 * 100%= 25%
The answer is 60 ml.
30 ml.
25 ml is roughly 4.2% of 600 ml
25% of 3 ml is 0.75 ml.
25%
125 ml 500(ml) * 0.05 = 25 25 / 0.20 = 125
To find 40 percent of 750 ml, you would first convert 40 percent to a decimal by dividing by 100, which gives you 0.40. Then, you would multiply 0.40 by 750 ml to get the answer. Therefore, 40 percent of 750 ml is 300 ml.
With 25ml methanol and 75ml water, there is 100ml in total. So there is 25/100 = 25% by volume methanol.
To calculate the volume percent concentration of propanol in the solution, we first need to find the total volume of the solution. This would be the sum of the volumes of propanol and water: 100 mL + 300 mL = 400 mL. The volume percent concentration of propanol in the solution is then calculated by dividing the volume of propanol by the total volume of the solution and multiplying by 100: (100 mL / 400 mL) * 100 = 25%. Therefore, the propanol concentration in the solution is 25% (v/v).
500 ml = 0.5 liter Answer = 0.5 x 100/25 = 2 %
The total volume of the solution is 48 mL + 144 mL = 192 mL. The percent by volume of ethanol is calculated as (volume of ethanol / total volume of solution) * 100%. Plugging in the values, we get (48 mL / 192 mL) * 100% = 25%. So, the solution contains 25% ethanol by volume.
