Problem data: m (mass of taken hydrogen) = 10 kg.

Reference values: M (molar mass of hydrogen) = 2.016 * 10-3 kg / mol; R (universal gas constant) = 8.31 J / (mol * K); P (standard pressure for gases, IUPAC) = 105 Pa; T (standard temperature for gases, IUPAC) = 273.15 K.

The volume that will take 10 kg of hydrogen, we calculate by the formula: V = m * R * T / (M * P).

Calculation: V = 10 * 8.31 * 273.15 / (2.016 * 10-3 * 105) = 112.6 m3.

Answer: Hydrogen will occupy a volume of 112.6 m3.
