If you wanted to combine equal numbers of na and cl atoms in a flask, how much cl would you have to add if you added 23g of na?

The mass of chlorine atom required to combine is 35.5 grams.

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

Given mass of sodium = 23 g

Molar mass of sodium = 23 g/mol

Putting values in equation 1, we get:

According to mole concept:

1 mole of an atom contains number of particles

So, 1 mole of sodium will contain = number of atoms

Number of atoms of chlorine = Number of atoms of sodium = = 1 mole

Now, calculating the mass of chlorine required by using equation 1:

Moles of chlorine = 1 mole

Molar mass of chlorine = 35.5 g/mol

Putting values in equation 1, we get:

Hence, the mass of chlorine atom required to combine is 35.5 grams.
