What is the difference between the soluble and insoluble substances​
Harrizon [31]

Soluble means that something will "dissolve" in a substance (typically water). This means that the substance is polar (like water)

insoluble is the opposite of soluble. It means that a substance will not dissolve in water. This means this is non-polar

Hope this helped!

) The volume of a balloon was 50,200 litres. If the temperature
Rudiy27

Answer:

1943.1 moles

Explanation:

From the question given above, the following data were obtained:

Volume (V) = 50200 L

Temperature (T) = 25 °C

Pressure (P) = 720 mmHg

Number of mole (n) of H₂ =?

Next, we shall convert 25 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Temperature (T) = 25 °C

Temperature (T) = 25 °C + 273

Temperature (T) = 298 K

Next, we shall convert 720 mmHg to atm. This can be obtained as follow:

760 mmHg = 1 atm

Therefore,

720 mmHg = 720 mmHg × 1 atm / 760 mmHg

720 mmHg = 0.947 atm

Thus, 720 mmHg is equivalent to 0.947 atm

Finally, we shall determine number of mole of Hydrogen gas, H₂, needed to fill the balloon as follow:

Volume (V) = 50200 L

Temperature (T) = 298 K

Pressure (P) = 0.947 atm

Gas constant (R) = 0.0821 atm.L/Kmol

Number of mole (n) of H₂ =?

PV = nRT

0.947 × 50200 = n × 0.0821 × 298

47539.4 = n × 24.4658

Divide both side by 24.4658

n = 47539.4 / 24.4658

n = 1943.1 moles
