how many moles of potassium bromide, kbr, are in 0.250 l of a 2.00 m solution?\nm = \\frac{mol}{l}\n? moles
how many moles of potassium bromide, kbr, are in 0.250 l of a 2.00 m solution?\nm = \\frac{mol}{l}\n? moles
Answer
Explanation:
Step1: Identify the formula
The formula for molarity is $M=\frac{\text{mol}}{\text{L}}$, and we need to solve for mol.
Step2: Rearrange the formula
We can rewrite the formula as $\text{mol}=M\times\text{L}$.
Step3: Substitute the given values
Given $M = 2.00\ M$ and $L=0.250\ L$, then $\text{mol}=2.00\ \frac{\text{mol}}{\text{L}}\times0.250\ \text{L}$.
Step4: Calculate the result
$2.00\times0.250 = 0.500$ mol.
Answer:
$0.500$ mol
