Aluminum metal reacts with bromine, a red-brown liquid with a noxious odor. the reaction is vigorous and produces aluminum bromide, a white crystalline substance. a sample of 27g of aluminum yields 266.7g of aluminum bromide. how many grams of bromine react with 18.1g of aluminum?

The mass of bromine reacted is 160.6 grams.

Explanation:

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

       .....(1)

Given mass of aluminium = 18.1 g

Molar mass of aluminium = 27 g/mol

Putting values in equation 1, we get:

The chemical equation for the reaction of aluminium and bromide follows:

By Stoichiometry of the reaction:

2 moles of aluminium reacts with 3 moles of bromine gas

So, 0.670 moles of aluminium will react with = of bromine gas.

Now, calculating the mass of bromine gas, we use equation 1:

Moles of bromine gas = 1.005 moles

Molar mass of bromine gas = 159.81 g/mol

Putting values in equation 1, we get:

Hence, the mass of bromine reacted is 160.6 grams.
