Answer:
Both molarity and molality involves number of moles of solute
Explanation:
Molarity is obtained by dividing the number of moles of solute by the volume of solution in liters. Note that a solution is formed when a solute is dissolved in a given volume of solvent.
Molality, of a solution is obtained by dividing the number of moles of a solute by the number of kilogrammes of solvent.
In both cases, the number of moles of solute is involved. Hence, the number of moles of solute present is common to both molarity and molality calculation.
<u>Answer:</u> The moles of oxygen and carbon dioxide in air is and respectively
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of atmosphere =
Average molar mass of atmosphere = 28.96 g/mol
Putting values in above equation, we get:
We know that:
Percent of oxygen in air = 21 %
Percent of carbon dioxide in air = 0.0415 %
Moles of oxygen in air =
Moles of carbon dioxide in air =
Hence, the moles of oxygen and carbon dioxide in air is and respectively
