We are not expected to do your homework here. Can't you grad a calculator and do these? Concerning the significant figures, you should know it, depending on the situation. But usually, stick to two or three sig fig.

[morga135]

as far as sig. figs. Are concerned, you would use three for this problem.

(0.102 x 0.0821 x 273)/1.01

since the first two zeros in the second number (0.0821) are to the left, they are not significant. Anything in the middle or to the right of the first non-zero digit, is significant.
