Ideal Gas Law and STP help?

Find the Volume at STP of a gas sample that occupies 245 mL (0.245 L) at 29 C (302 K) at 1.51 atm.

So... using the ideal gas law, we can set up the equation.

(1.51 atm) (0.245 L) = n (0.08206 - constant) (302 K)

And n = 0.01493. Now what? What does it mean find the volume at STP?

    STP stands for standard temp and pressure.

    This is 0 deg celcius and 1 atm

    You've done the other work correctly, so now just enter the moles into the equation with the values of Temp and pressure at STP to find the new volume

    "equivalent volumes of gas comprise equivalent numbers of molecules."--Avogadro Atomic weights: C=12 O=sixteen CO2=40 4 2.75LCH4 x 1LCO2/1LCH4 x 1molCO2/22.4LCO2 x 44gCO2/1molCO2 = 5.40g CO2 to 3 substantial figures
