Please help! I know it is a lot of calculations, but even if you could just show my the steps for a few of the questions it would be a great help especially in solving mmolHA, mmmol A mmmol H30 please!!!
Question 1 and 2 are solved , with explanation so I think you would be able to solve 3 and 4 as the question involve too much calculation and it has to be done in the same way
