Ideal gas equation

I just want to check that my answer is correct:
pV=nRT where R is the gas constant 8.31 J mol-1 K-1
1) convert 103 KPa to Pa =103,000
2)convert 50cm3 to m3 =0.00005
3)convert 28 degrees to K =301.15
4) Calculate the numbers of moles under these conditions to the correct number of significant figures = I got as my final answer 485.93 moles

n = PV / RT

You did n = RT / PV.

1/ your answer = 0.0021 mol

SF should be 2.
