Question

how many moles is 24.5 g of silver?
0.227 mol
4.40 mol
83.4 mol
2640 mol

Explanation:

Step1: Recall the formula for moles

The formula for calculating the number of moles ($n$) is $n=\frac{m}{M}$, where $m$ is the mass and $M$ is the molar mass.

Step2: Find the molar mass of silver

The molar mass of silver ($Ag$) is $M = 107.87\ g/mol$.

Step3: Substitute values into the formula

Given $m = 24.5\ g$, we substitute into $n=\frac{m}{M}$: $n=\frac{24.5\ g}{107.87\ g/mol}\approx0.227\ mol$.

Answer:

0.227 mol
