Answer:
The soluble in water are a and b. c is not soluble in water
Explanation:
The water solubility of a compound, it depends its polarity (. KHSO4 has several polar molecules, actually it has ions charged positively like K and H, and charged negatively like sulfate (SO4-2). When it happens, molecules can do hydrogen bridges with water. It is because of above, KHSO4 can be used in wine making. Something similar happens with propylen glycol but in this case the polar part is OH- ions. Benzene has not polar parts. It is totally apolar compound.

Impulse is the product of a force and the time during which that force acts on a body.
Answer:
54.72 g
Explanation:
Mass = ?
Volume = 5.61 L
Pressure = 5.66 atm
Temperature = 311 K
The relationship between these equations is given by the ideal gas equation;
PV = nRT
where R = gas constant = 0.0821 atm L K-1 mol-1
n = PV / RT
n = 5.66 * 5.61 / (0.0821 * 311 )
n = 1.2436 mol
Number of moles = Mass / Molar mass
Mass = Number of moles * Molar mass = 1.2436 * 44 = 54.72 g
