Calculate the volume of each of the following gas sample at STP

a. 45.1 mL, 241 c 755 mm Hg
b. 4.31 L, 72.1 c, 0.890 atm
5.12 mL, 289 K, 91.2 kPa
d. 91.3L , 451C , 145 atm

Please put extra information of how the formula works.

PV=nRT
pressure x volume = #of moles x R(its a constant) x temp

STP
standart temp and pressure
temp=25C press= 1 atm

can you get it from there?
