Question

Given the mass of 0.2 moles of bromine (Br) atom: 16 g. Taking N₁ = 6 x 10²³ Deduce its atomic mass of bromine. ​

Answer 1

80 g/mol

Step-by-step explanation:

The atomic mass of bromine can be calculated using the formula:

Atomic Mass (g/mol) = (Mass of the sample (g)) / (Number of moles)

In this case, you have the mass (16 g) and the number of moles (0.2 moles). Now, u can calculate the atomic mass:

Atomic Mass of Bromine = (16 g) / (0.2 moles) = 80 g/mol

So, the atomic mass of bromine is 80 g/mol
