A 0.58 g0.58\,\text{g} sample of an ideal gas at 100 kPa100\,\text{kPa} and 100∘C100^\circ\text{C} has a volume of 250 cm3250\,\text{cm}^3. Which expression is equal to the molar mass of the gas? (1) 0.58×8.31×100100×103×250×10−6\frac{0.58\times8.31\times100}{100\times10^3\times250\times10^{-6}} (2) 0.58×8.31×373100×103×250×10−6\frac{0.58\times8.31\times373}{100\times10^3\times250\times10^{-6}} (3) 0.58×100×10−3×250×1068.31×100\frac{0.58\times100\times10^{-3}\times250\times10^6}{8.31\times100} (4) 0.58×100×10−3×250×1068.31×373\frac{0.58\times100\times10^{-3}\times250\times10^6}{8.31\times373}
