Question

What is the pressure, in Pa, if 3 mol of gas occupies \({\text{500 c}}{{\text{m}}^{\text{3}}}\) at 25 °C?

Given:     \(R = 8.31{\text{ J}}\,{{\text{K}}^{ - 1}}{\text{mo}}{{\text{l}}^{ - 1}}\)

     \({10^{ - 3{\text{ }}}}{{\text{m}}^3} = {10^3}{\text{ c}}{{\text{m}}^3}\)

A.     \(\frac{{3 \times 8.31 \times 298}}{{500}}\)

B.     \(\frac{{3 \times 8.31 \times 25}}{{0.0005}}\)

C.     \(\frac{{3 \times 8.31 \times 25}}{{500}}\)
