    In the condition known as acidosis, the blood pH would be:
    The healthy pH range for blood is 7.35–7.45. A pH value below this, while still alkaline, indicates insufficient alkalinity (or too much acidity) and is termed acidosis.

    Which strategy would be most effective in dealing with a severe case of dehydration?
    IV solutions should be isotonic (oral solutions should be hypotonic). Glucose would be absorbed by cells leaving the water behind in the blood which would reduce blood osmolarity. Hence water would redistribute itself by osmosis through the body.

    Ribose is a sugar with molecular formula C5H10O5. Given that the atomic weights are C = 12, H = 1 and O = 16, how many moles of ribose are there in 3 g?
    Mass of 1 mol of ribose = (5 × 12) + (10 × 1) + (5 × 16) = 60 + 10 + 80 = 150 g. 3 g is less than 1 mol. Number of moles = 3 g/150 g per mol = 0.02 mol.
