Answer
$n=106$ mol
Work Step by Step
We will use the ideal gas equation to solve this question:
$PV=nRT$
Since we need to find $n$, we will rearrange this equation to make $n$ the subject of the formula:
$n=\frac{PV}{RT}$
To use this equation, we need to convert the temperature to Kelvin:
$T=273K+10=283K$
Substituting the values into the rearranged formula above, we get
$n=\frac{100\times10^3(2.5)}{8.314(283)}$
$n=106$ mol
