250 ml glass of lemon juice contains 20 grams of sugar. How much sugar is in 500 ml bottle
iren2701 [21]

There is 40 g of sugar in a 500 ml bottle of lemon juice

<h3>Further explanation</h3>

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight/volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.

the concentration of sugar in lemon juice :

\tt \dfrac{20~g}{250~ml}=0.08~g/ml

So for 500 ml juice :

\tt 500\times 0.08=40~g~sugar
