how many moles of iodine should be added to 750 grams of carbon tetrachloride to prepare a 0.24 m solution

aleksley [76]

Answer:

0.18 mol

Explanation:

Given data

Mass of carbon tetrachloride (solvent): 750 g

Molality of the solution: 0.24 m

Moles of iodine (solute): ?

Step 1: Convert the mass of the solvent to kilograms

We will use the relationship 1 kg = 1,000 g.

$750g \times \frac{1kg}{1,000g} =0.750kg$

Step 2: Calculate the moles of the solute

The molality is equal to the moles of solute divided by the kilograms of solvent. Then,

$m = \frac{moles\ of\ solute }{kilograms\ of\ solvent} \\moles\ of\ solute = m \times kilograms\ of\ solvent = \frac{0.24mol}{kg} \times 0.750kg = 0.18 mol$

A sample of oxygen gas (O2) has a volume of 7.51 L at a temperature of 19°C and a pressure of 1.38 atm. Calculate the moles of O

Maslowich

Answer: 0.43molO₂

Explanation:

The ideal gas law for moles is $n=\frac{PV}{RT}$ . If you did not know, R is the ideal gas constant, $0.0821\frac{L*atm}{mol*K}$ .

Since the temperature must be in Kelvin, we must convert our given temperature from ℃ to K. $19C+273=292K$

Now that we have the temperature converted to Kelvin, we can plug in our information to the ideal gas law for the number of moles.

$n=\frac{PV}{RT}$

$n=\frac{1.38atm*7.51L}{0.0821\frac{L*atm}{mol*K} *292K} =0.43molO_{2}$

$n=0.43molO_{2}$

Therefore, the number of moles is 0.43molO₂.
