wow I'm dumb... What is the approximate density of glucose?

    I've been making drinks for use after training sessions whichg contain glucose, maltodextrin, whey protein and egg protein.
    For no partiucular reason, I absent-mindedly assumed that the density of all these substances is the same as water. I only copped onto this last night and I realised that I had been taking about a third as much whey protein as I thought, and half as much maltodextrin. (eg: 40 ml whey protein instead of 40g).
    I can't find the density of glucose. I don't have a scales. If anyone happens to know it, please tell me. I also am not sure what the density of egg white powder is.

    Glucose is 180gm/mole. I think you might need to use the Baumé scale to find out it's mg to ml conversion. As for the egg white powder I'm not sure. Lana's egg whites or one of those sites may have it listed though.

    Did a bit of digging on specific gravity and think it may be approx. 1.4g/ml.

    I don't understand that.
    500g bag of glucose = 12.5 70ml scoops of glucose = 875ml

    density = .57

    edit:

    thanks for that.
    Don't know why the figures are so different.
    Found a site that says the density is 1.6

    Seemed too high I thought. compared bag of glucose with (same) bag of water and water was definitely heavier.

    You divided it the wrong way. It's gm/ml you're looking for so it's 875/500=1.75

    Given that the bag wn't be 100% pure glucose it's closer to 1.5gm/ml I'd say.

    And specific gravity of glucose ranges in values so you can get anything from 1.4gm/ml to 1.6gm/ml.

    500 gm / 875 ml

    if glucose syrup is a different form of the same substance, then maybe that is what has the higher density.

    Ah I get you now. Glucose syrup is a suspension so could be any strength.
