    This is where those crazy solution concentrations in medicine come in, you just can not say percent, you have to state the basis. Commonly, (in idiot medical terms), these are w/v. So I assume you are using w/v

    .05 w/v or with 500ml, then you have 25g sugar, and 4.5g salt

    I have never understood why w/v is used, I guess since it eliminates density, it is easier, afterall, who wants to worry with density?
