<span>Coca-cola is similar to tomato juice because both are acidic drinks. Coca-cola is acidic because it is a carbonated drink. This means there is a presence of an acid in coke namely: carbonic acid and phosphoric acid. Tomato juice is also acidic because of the presence of vitamin c (ascorbic acid), but slightly less acidic than coke.</span>
Answer:
49.0g/mol is molar mass of X
Explanation:
<em>551mg of X are dissolved in 100g of benzonitrile</em>
<em>Freezing point of solution: -13.4°C</em>
The freezing point depression of a solution (Colligative property) follows the equation:
ΔT = Kf*m*i
<em>Where ΔT is change in freezing point from the pure solvent (Benzonitrile: -12.8°C) to the solution (-13.4°C)</em>
<em>Kf is freezing point depression of benzonitrile: 5.34°C/m</em>
m is molality of the solution (Moles X / kg of benzonitrile)
And i is Van't Hoff factor (1 for any solute in benzonitrile)
ΔT = -12.8°C - (-13.4°C) = 0.6°C
Solving for molality of the solution:
ΔT = Kf*m*i
0.6°C = 5.34°C/m*m*1
0.1124m = molality of the solution
Moles of X are:
0.1124mol/kg benzonitrile * 0.1kg benzonitrile = 0.01124 moles X
In 551mg = 0.551g:
Molar mass:
0.551g / 0.01124mol =
49.0g/mol is molar mass of X
Answer:
i.elements not obeying increasing atomic mass. ii.properties and uneven grouping.
Answer:
Explanation: a simple solution is basically two substances that are evenly mixed together. one of them is called the solute and the other is the solvent. solute is the substance to be dissolved (sugar).
am not sure if that is the answer but hopefully it helps.
