Answer:
267.57 kPa
Explanation:
Ideal gas law:
PV = n RT R = 8.314462 L-kPa/K-mol
P (16.5) = 1.5 (8.314462)(354) P = 267.57 kPa
M = 22.8 g
V = 14.7 mL
ρ - ?
ρ = m/V
ρ = 22.8/14.7 = 1.55 g/mL
Answer:
1.4 g/cm3
Explanation:
Density = Mass/Volume
Mass = 21g
Volume = 15cm3
Density = 21/15 = 1.4
Answer:
5 g/cm^3
Explanation:√3V=1.91293cm
They all are correct , so with that being said anyone of them can be right
