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 :

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

How many molecules are in 5.60 L of oxygen gas

topjm [15]

5.6L of O2 means we have 0.25 moles of O2.
As, 1 mole has 6.023*10^23 molecules,
0.25 moles of O2 will have 0.25*6.023*10^23 molecules=1.50575*10^23 molecules
and as 1 molecule of O2 has 2 atoms, so, 1.50575*10^23 molecules will have 2*1.50575*10^23 atoms=3.0115*10^23 atoms of O.
