Question

DAU COROANA !!! URGENT !!!

Determinati densitatea unui amestec de 4 g de heliu si 28 g de azot la temperatura de 300 K si presiunea de 100 kPa

Answer 1

μ=m/υ=(m1+m2)/(υ1+υ2)=(m1+m2)/(m1/μ1+m2/μ2)=(4+28)/(4/4+28/28)=32/2=16 g/mol=0,016 kg/mol

ρ=m/V=μυp/υRT=μp/RT=0,016*10⁵/8,314*300=0,65 kg/m³
