Answer:
Explanation:
Chemistry is the study of matter and the changes that matter undergoes. Matter is anything that has mass and takes up space.
From Ideal Gas Equation
PV = nRT
V = nRT/ P
= (0.5/12)*0.82*-20/1.5
=0.042*0.82*-20/1.5
Volume = 0.46
Density = 0.5/0.46
= 1.08 gm/cc
( Option D)
MgCl2
Charges are not included in chemical formulas- they are implied
