STP is defined as 1 bar and 0 °C.
The molar volume at STP is 22.71 L/mol.
$"Moles of Ne" = 36.2 color(red)(cancel(color(black)("g Ne"))) × "1 mol Ne"/(20.18 color(red)(cancel(color(black)("g Ne")))) = "1.794 mol Ne"$
∴ The volume of neon is
$V = 1.794 color(red)(cancel(color(black)("mol Ne"))) × "22.71 L Ne"/(1 color(red)(cancel(color(black)("mol Ne")))) = "40.7 L Ne"$
