Hey there!:
mass = 41.2 g
Volume = 8.2 cm³
Therefore:
D = m / V
D = 41.2 / 8.2
D = 5.02 g/cm³
Answer:
D
Explanation:
According to Avogadro's law, equal volumes of different gases at the same temperature and pressure have equal number of molecules.

Explanation:
Given 500 cm^3 = V1 760 mm = P1 (760*2) = P2
Required V2
P1V1 = P2V2
RE-ARRANGE TO P1V1/P2 = V2
(760)(500) /(760*2) = V2
V2 = 250 ML
