Question

What volume, in \({{\text{m}}^{\text{3}}}\), is occupied by 2.00 mol of gas at 27 °C and 2.00 atm pressure?

Assume: \({\text{1.00 atm}} = 1.01 \times {10^5}{\text{ Pa}}\) and \(R = 8{\text{.}}31{\text{ J}}\,{{\text{K}}^{ - 1}}{\text{mo}}{{\text{l}}^{ - 1}}\).

A.     \(\frac{{8.31 \times 27}}{{1.01 \times {{10}^5}}}\)

B.     \(\frac{{2.00 \times 8.31 \times 27}}{{1.01 \times {{10}^5}}}\)

C.     \(\frac{{2.00 \times 8.31 \times 300}}{{2.00 \times 1.01 \times {{10}^5}}}\)

D.     \(\frac{{2.00 \times 8.31 \times 300}}{{1.01 \times {{10}^5}}}\)
