Answer : The volume of CO_2 will be 0.4665 L

Solution : Given,

Initial volume = 500 ml = 0.5 L         (1 L = 1000 ml)

Initial pressure = 742 torr = \frac{742}{760}=0.976atm    (1atm=760torr)

Final pressure = 795 torr = \frac{795}{760}=1.046atm

According to the Boyle's law, the pressure of the gas is inversely proportional to the volume of the gas at constant temperature.

P\propto \frac{1}{V}

or,  \frac{P_1}{P_2}=\frac{V_2}{V_1}

where,

P_1 = initial pressure of the gas

P_2 = final pressure of the gas

V_1 = initial volume of the gas

V_2 = final volume of the gas

Now put all the given values in the above formula, we get

\frac{P_1}{P_2}=\frac{V_2}{V_1}

\frac{0.976atm}{1.046atm}=\frac{V_2}{0.5L}

By rearranging the terms, we get the final volume of the gas.

V_2=0.4665L

Therefore, the volume of CO_2 will be 0.4665 L

Answer: 466.67 ml

Explanation:

Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

P\propto \frac{1}{V}   (At constant temperature and number of moles)

Thus

P_1V_1=P_2V_2  [according to Boyle's law]

742torr\times 500ml=795torr\times V_2

V_2=466.67ml

Consider the following gas phase reaction:
snow_tiger [21]

Answer:

2NO(g) + O2(g) --> 2NO2(g)

now 400 ml of NO × 2 mol of NO2/2 mol of NO

= 400 ml of NO2

now 500 ml of O2 × 2 mol of NO2/1 mol of O2

= 1000 ml of NO2

now 400 ml of NO2 × 1 mol of O2/2 mol of NO

= 200 ml

subtract that from 500 ml of total i.e. 500-200 =300 ml

The total volume of the reaction mixture is 1000 ml -300ml = 700 ml

According to table g, which substance forms an unsaturated solution when 80. grams of the substance are stirred into 100. grams
e-lub [12.9K]

A saturated solution is one in which no more solute is able to dissolve in a given solvent at a particular temperature. Some amount of the solute is left undissolved in the solution.

Unsaturated solution has solute in lower proportions than required to form a saturated solution.

Supersaturated solution has solute in amounts greater than a saturated solution.

We can take the help of solubility curve in order to find out the amount of a salt required to prepare a saturated solution of that salt at a particular temperature.

The solubility of KI at 10^{0}C is 136 g/ 100 mL water

The solubility of KNO_{3} at 10^{0}C is 21 g/100 mL water.

The solubility of NaNO_{3} at 10^{0}C is 80 g/100 mL water.

The solubility of NaCl at 10^{0}C is 38 g/ 100 mL water.

So the correct answer will be KI, as it would need 136 g KI / 100 mL water to form a saturated solution at 10^{0}C.So, if we have 80g KI/ 100mL water it would be an unsaturated solution.
