1.7(a) In an attempt to determine an accurate value of the gas constant, R, a student heated a container of volume 20.000 dm filled with 0.251 32 g of helium gas to 500°C and measured the pressure as 206.402 cm of water in a manometer at 25°C. Calculate the value of R from these data. (The density of water at 25°C is 0.997 07 g cm; the construction of a manometer is described in Exercise 1.6a.)
