Molarity = mol/L
500 mL = 0.5 L

342.34 g/mol * 0.462 mol/L = 158.16 g/L
158.16 g/L * 0.5 L = 79.1 g of sucrose is needed to create a 0.462 M solution.

A glass holds 6 ounces of 60-proof rum (30 alcohol). how much fruit juice must be added to the rum so that the mixture is dilute
Elenna [48]

We need an equation that will relate the concentrated mixture and the diluted one. To solve this we use the equation, 

M1 V1 = M2 V2

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

M1V1 = M2V2

30 % x 6 oz = 20 %  x V2

V2 = 9 oz 


The volume of the diluted mixture would be 9 oz. Therefore, you will need to add 9 oz - 6 oz = 3 oz of fruit juice to dilute the 30 percent alcohol to 20 percent alcohol.

One mole of an ideal gas is expanded from a volume of 1.00 liter to a volume of 6.43 liters against a constant external pressure
Bingel [31]
We actually don't need the value for temperature. There is a direct formula relating work, pressure and volume. The relationship is:

W = Pexternal(ΔV)

Substituting the values and incorporating the conversion ratio,

W = (1 atm)(6.43 L - 1 L)(101.3 J/1 L·atm)
<em>W = 651.36 J</em>
