Direction: Rahul took 5 moles of carbon atoms in a container and Soha...
Explanation:
To determine which container is heavier, we need to compare the molar masses of carbon and sodium.
Molar Mass:
- Molar mass is the mass of one mole of a substance. It is expressed in grams per mole (g/mol).
- The molar mass of an element is equal to its atomic mass.
Carbon (C):
- Atomic mass of carbon (C) = 12.01 g/mol
Sodium (Na):
- Atomic mass of sodium (Na) = 22.99 g/mol
Moles:
- A mole is a unit of measurement to represent a specific number of atoms, molecules, or ions.
- One mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23.
Given Information:
- Rahul has 5 moles of carbon atoms.
- Sohan has 5 moles of sodium atoms.
Calculation:
To compare the weights of the containers, we need to calculate the total mass of each container.
Carbon Container:
- Number of moles of carbon = 5
- Molar mass of carbon (C) = 12.01 g/mol
- Total mass of carbon = Number of moles * Molar mass = 5 * 12.01 = 60.05 g
Sodium Container:
- Number of moles of sodium = 5
- Molar mass of sodium (Na) = 22.99 g/mol
- Total mass of sodium = Number of moles * Molar mass = 5 * 22.99 = 114.95 g
Comparison:
- Total mass of carbon container = 60.05 g
- Total mass of sodium container = 114.95 g
Since the total mass of the sodium container (114.95 g) is greater than the total mass of the carbon container (60.05 g), we can conclude that the 5 moles of sodium container is heavier than the 5 moles of carbon container.
Therefore, the correct answer is option B) 5 moles of sodium container.

Therefore, the correct answer is option B) 5 moles of sodium container.
