Answer: The pressure of an ideal gas 0.278 atm.

Explanation:

Volume of the ideal gas ,V = 35.5 L

Pressure of an ideal gas,P = 0.138 atm

Temperature of an ideal gas = 223 K

Number of moles of an ideal gas = 0.540 mol

Ideal gas equation is given as:

PV=nRT

P=\frac{n}{V}\times RT=\frac{0.540 mol}{35.5 L}\times 0.0820 atm l/mol K\times 223 K

P = 0.278 atm

The pressure of an ideal gas 0.278 atm.

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
