At room temperature, the solubility of which solute in water would be most affected by a change in pressure?
Bad White [126]
<h3><u>Answer;</u></h3>

At room temperature, the solubility of which solute in water would be most affected by a change in pressure?

<h3><u>Explanation;</u></h3>
  • As the pressure on a gas confined above a liquid increases, the solubility of the gas increases in the liquid.
  • Carbon dioxide gas is most soluble in water under conditions of high pressure and low temperature.
  • The solubility of gases decreases with increasing temperature, so the air space inside the cylinder when cold water is used will be less compared to warm water.

What is the mass of 1 L of a gas at STP whose molar mass is 254 g/mol?
inysia [295]
The volume of 1 mole of gas is always 22.4 dm3. Molar volume= Volume/number of moles (first we should discover the number of mole) so 22.4 =1/number of moles <=> number of moles=1/22.4 moles

Now that we know the number of moles we can use the formula Molar Mass= mass /number of moles <=> 254= mass/(1/22.4) so mass =254/22.4 <=> mass= 11.339 which is 11.3 g
