What change would increase the amount of gas able to be dissolved in a given amount of liquid water?
butalik [34]
It would be the change in pressure that would <span>increase the amount of gas able to be dissolved in a given amount of liquid water. Increasing the pressure of a system would allow more gas to be dissolved into a liquid. Hope this answers the question. Have a nice day.</span>

The following properties are either physical or chemical. Which one is different from the rest based on those two categories?
wel
Chemical properties can only be analyzed by putting the substance through a chemical reaction, such as combustion.
Physical properties can be analyzed without altering the substance chemically. With that in mind:

Boiling point: physical
Density: physical
Ductility: physical
Heat of combustion: chemical

When 0.49 g of a molecular compound was dissolved in 20.00 g of cyclohexane, the freezing point of the solution was lowered by 3
IRISSAK [1]

Answer: The molecular mass of this compound is 131 g/mol

Explanation:

Depression in freezing point:

\Delta T_f=i\times k_f\times \frac{w_2\times 1000}{M_2\times w_1}

where,

\Delta T_f = depression in freezing point  = 3.9^oC

k_f = freezing point constant  = 20.8^0C/m

m = molality

i = Van't Hoff factor = 1 (for non-electrolyte)

w_2 = mass of solute = 0.49 g

w_1 = mass of solvent (cyclohexane) = 20.00 g

M_2 = molar mass of solute = ?

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

(3.9)^oC=1\times (20.8^oC/m)\times \frac{(0.49g)\times 1000}{M_2\times (20.00g)}

M_2=131g/mol

Therefore, the molar mass of solute is 131 g/mol
