Answer:
The mass of dioxygen is 70.6 g.
The molar mass of dioxygen is 32 g/mol.
=70.6 g/32 g/ mol=2.21mol
The number of moles of dioxygen
The mass of neon is 167.5 g
The molar mass of neon is 20.2 g/mol.
The number of moles of neon
=167.5 g/20.2g/mol = 8.29 mol
The total number of moles of neon and dioxygen
The mole fraction of neon = 8.29/ 10.49 = 0.789
Total pressure in the cylinder is 25 bar.
The partial pressure of neon = 0.789× 25 bar = 19.7bar
The partial pressure of dioxygen = 25bar - 19.7bar = 5.3 bar
