Answer:
The unknown temperature is 304.7K
Explanation:
V1 = 100mL = 100*10^-3L
P1 = 99.10kPa = 99.10*10³Pa
V2 = 74.2mL = 74.2*10^-3L
P2 = 133.7kPa = 133.7*10³Pa
T2 = 305K
T1 = ?
From combined gas equation,
(P1 * V1) / T1 = (P2 * V2) / T2
Solving for T1,
T1 = (P1 * V1 * T2) / (P2 * V2)
T1 = (99.10*10³ * 100*10^-3 * 305) / (133.7*10³ * 74.2*10^-3)
T1 = 3022550 / 9920.54
T1 = 304.67K
T1 = 304.7K

"Glycerin" is the one substance among the following choices given in the question that will <span>float in corn syrup. The correct option among all the options that are given in the question is the second option or option "B". I hope that this is the answer that has actually come to your desired help.</span>
The molality of the solution is a measure of its concentration that can be calculated by dividing the amount of substance in moles by the amount of the solvent in kilograms. Mathematically, this can be expressed as that of the equation below.
molality = amount of solute (mole) / amount of solvent (kg)
molality = 5 moles / 3.2 kg
molality = 1.5625 m
Rounding off the answer to the nearest tenths, will give the final answer of <em>1.6 m</em>.
