What is the volume occupied by #"10.23"# moles of nitrogen gas at STP?
STP conditions are currently defined as a pressure of
In other words, if you know how many moles of gas you have under STP conditions, you can use the molar volume of a gas, which is equal to
In your case, the sample contains
#10.23 color(red)(cancel(color(black)("moles N"_2))) * overbrace("22.71 L"/(1color(red)(cancel(color(black)("mole N"_2)))))^(color(blue)("molar volume of a gas at STP")) = color(green)(|bar(ul(color(white)(a/a)color(black)("232.3 L")color(white)(a/a)|)))#
The answer is rounded to four sig figs.
SIDE NOTE More often than not, the definition of STP conditions will be given to you as a pressure of
Under these conditions, the molar volume of a gas is equal to
