Question

question 2 (1 point) how many moles of kbr are in 59.1 grams? report your answer in moles but do not include units in your response. your answer: answer

Explanation:

Step1: Find molar mass of KBr

The molar mass of K (potassium) is approximately 39.1 g/mol and Br (bromine) is approximately 79.9 g/mol. So molar mass of KBr, $M = 39.1+79.9=119$ g/mol.

Step2: Calculate moles

Use the formula $n=\frac{m}{M}$, where $m = 59.1$ g and $M = 119$ g/mol. So $n=\frac{59.1}{119}\approx0.497$.

Answer:

0.497
