He: $0.5\text{ atm}$ Ne: $0.3\text{ atm}$ Ar: $0.2\text{ atm}$
Total Number of Particles = 10 Number of He Particles = 5 Number of Ne Particles = 3 Number of Ar Particles = 2 Partial Pressure of He = $1.0\text{ atm}*\frac{5}{10}=0.5\text{ atm}$ Partial Pressure of Ne = $1.0\text{ atm}*\frac{3}{10}=0.3\text{ atm}$ Partial Pressure of Ar = $1.0\text{ atm}*\frac{2}{10}=0.2\text{ atm}$
