Question

what is the mass of 2.75 moles k₂s? molar mass k₂s = 110.27 g/mol

Explanation:

Step1: Recall the formula

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

Step2: Substitute the values

Given \(n = 2.75\space mol\) and \(M=110.27\space g/mol\), substitute into the formula: \(m = 2.75\space mol\times110.27\space g/mol\).

Step3: Calculate the result

\(m=2.75\times110.27 = 303.2425\space g\).

Answer:

\(303.24\space g\) (rounded to four significant figures)
