Question

what is the mass of 0.25 mol of koh?
molar mass koh = 56.11 g/mol
0.25 mol koh = ? g koh

Explanation:

Step1: Recall the formula

The formula for calculating mass \(m\) from moles \(n\) and molar mass \(M\) is \(m = n\times M\).

Step2: Substitute the values

Given \(n = 0.25\space mol\) and \(M=56.11\space g/mol\), substitute into the formula: \(m=0.25\space mol\times56.11\space g/mol\).

Step3: Calculate the result

\(m = 0.25\times56.11=14.0275\space g\).

Answer:

\(14.0275\space g\)
