What is the pressure, in Pa, inside a 1.0 m³ cylinder containing 10 kg of H₂ (g) at 25 ºC?

R = 8.31 J K^–1 mol^–1; pV = nRT

A. \(\frac{{1 \times {{10}^4} \times 8.31 \times 25}}{{1.0 \times {{10}^3}}}\)

B. \(\frac{{5 \times {{10}^2} \times 8.31 \times 298}}{{1.0}}\)

C. \(\frac{{1 \times 8.31 \times 25}}{{1.0 \times {{10}^3}}}\)

D. \(\frac{{5 \times {{10}^3} \times 8.31 \times 298}}{{1.0}}\)
