Hello everyone, so the question says that a doctor orders 200 ml of ibuprofen.
00:11
So, volume of solution here, volume of solution here is 200 ml and the percentage, now the question says if you have 8 % molar by volume ibuprofen, then how many milliliters do you need? that means we have been given the percentage that is 8 and we have to find out the volume here.
00:48
So now we know that the percentage, the molar by volume percentage can be calculated by using the formula.
01:02
Molar by volume percentage, it can be calculated by using the formula.
01:08
Mass of the solute.
01:11
Mass of the solute mass of the solute divided by volume of solution divided by volume of solution volume of solution multiplied by 100 that gives smaller by volume percentage as we have the data in the question the volume of the solution that we have and molar by volume percentage that is also.
01:53
So we can predict the mass of the solute.
01:56
So mass of the solute will be, mass will be your molar by volume percentage multiplied by volume of solution, volume of solution divided by 100...
