Question

3. Calculate how many grams of bromine are in 3.28 moles of bromine.

Answer 1

There is 262.4 grams of Br in 3.28 moles of Br.

Step-by-step explanation:

• As we know, 6.023*10^23 atoms or molecules of any element is equal to its atomic or molecular weight. And, 6.023*10^23 atoms of any element is also equal to 1 mole of the same element.
• 1 mole of an element Br is equal to 79.904 nearly 80 grams.
• 3.28 moles of Br is equal to 3.28* 80 grams
• Therefore, 3.28 moles of Br is equal to 262.4 grams of Br.
• Or, we can say there is 262.4 grams of Br in 3.28 moles of Br.
