Question

If 3.50 moles of Br2 are used, how many grams of KBr are formed? 2 K + 1 Br2 --> 2 KBr
​

Answer 1

Step-by-step explanation:

2 K + 1 Br₂ ⇒ 2 KBr

Use the balanced equation and the molar mass of KBr to find grams of KBr formed from 3.50 moles of Br₂.

Note that all units cancel except grams of KBr, which is what is being asked.

3.50 mol Br₂ x (2 mol KBr/1 mol Br₂) x (119.00 g KBr/1 mol KBr) = 833 g KBr
