Question

6. In a chemical atomic mass determination, the tin content of 3.7692 g SnCl4 was found to be 1.7170 g. If the atomic mass of chlorine is taken as 35.453, what is the value for the atomic mass of the tin isolated during this experiment? ​

Answer 1

To determine the atomic mass of tin, we need to subtract the mass of chlorine from the total mass of tin chloride.

Step-by-step explanation:

To determine the atomic mass of tin, we need to use the concept of average atomic mass.

The atomic mass of an element is the weighted average of the masses of its isotopes, based on their relative abundance.

In this case, we know the mass of tin chloride (SnCl4) and the mass of chlorine, so we can find the mass of tin.

First, calculate the molar mass of tin chloride: mass of tin (Sn) + 4 * mass of chlorine (Cl)

Given that the mass of tin chloride is 3.7692 g and the mass of chlorine is 1.7170 g, we can subtract the mass of chlorine from the total mass to find the mass of tin.

So, the atomic mass of tin isolated during this experiment is 2.0522 g.
