Question

Which of the following has the smallest mass:

6.022 X 1023 molecules of Cl₂
85.0 g of Cl₂
1.50 mol of Cl₂
0.050 kg of Cl₂

Answer 1

To determine which of the given options has the smallest mass of chlorine (Cl₂), we need to compare the molar mass of each.

Step-by-step explanation:

To determine which of the given options has the smallest mass of chlorine (Cl₂), we need to compare the molar mass of each.

First, let's convert the given quantities to moles:

1. 6.022 x 10²³ molecules of Cl₂ is equal to 1 mole of Cl₂
2. 85.0 g of Cl₂ is equal to 1.20 moles of Cl₂
3. 1.50 mol of Cl₂ is the same as 106.5 g of Cl₂
4. 0.050 kg of Cl₂ is equivalent to 70.90 moles of Cl₂

From the above conversions, we can see that the smallest mass of Cl₂ is found in option 6.022 x 10²³ molecules of Cl₂, as it corresponds to 1 mole of Cl₂. Therefore, this option has the smallest mass.
