You have a 70% dextrose solution. How many grams of dextrose are in 400ml?
It depends upon the density of the solution. If 400 ml weighs 400g (as it would for water), then 70% of that would be the mass of dextrose, assuming the "%" refers to the mass fraction.
thanks for the input!
To calculate the grams of dextrose in a 70% dextrose solution, you need to multiply the percentage by the volume of the solution in milliliters.
Step 1: Convert the percentage to a decimal by dividing it by 100. In this case, 70% becomes 0.7.
Step 2: Multiply the decimal by the volume of the solution. In this case, the volume is 400 ml.
Calculation: 0.7 x 400 = 280
Therefore, there are 280 grams of dextrose in 400 ml of a 70% dextrose solution.
