Answer:
a. Molarity=
b. Molality=
Explanation:
Hello,
In this case, given the information about the aniline, whose molar mass is 93g/mol, one could assume the volume of the solution is just 200 mL (0.200 L) as no volume change is observed when mixing, therefore, the molarity results:
Moreover, the molality:
Best regards.
<u>Answer:</u> The mass of carbon monoxide required is 1.094 kg
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of iron (III) oxide = 2.08 kg = 2080 g (Conversion factor: 1 kg = 1000 g)
Molar mass of iron (III) oxide = 159.69 g/mol
Plugging values in equation 1:
The given chemical equation follows:
By the stoichiometry of the reaction:
If 1 mole of iron (III) oxide reacts with 3 moles of CO
So, 13.02 moles of iron (III) oxide will react with = of CO
Molar mass of CO = 28.01 g/mol
Plugging values in equation 1:
Hence, the mass of carbon monoxide required is 1.094 kg
