false
Explanation:
Inertia is the resistance of any physical object to any change in its velocity, so it can't move by itself. Only by a different entity.

Explanation:
Answer:
d) 44 g/mol
Explanation:
If we can consider that this gas behaves like an ideal gas, then we can use the following formula:
PV=nRT
P=pressure
V=volume
n=N° of moles
R= gas constant, it has multiple units, for this case, we will use 62.36 mmHg*Lt/mol*K
Then, the number of moles can also be noted as:
n=m/M , where m=mass and M=molar gas so: PV=(m/M)RT
M=(mRT)/(PV)
And we have the rest of the values for this case:
T=0°=273°K
V=1Lt
P=238 mmHg
m=0.614 g
If we finally put all these values in our formula, we can get the molar mass for this gas:
M=(0.614x62.36X273)/(273x1) gxmmHgxLtx°K/molx°K/(mmHgxLt)
M= 44 g/mol
