The density of a sample of nitrogen gas (N₂) that exerts a pressure of 5.30 atm in a 3.50-L container at 125°C is 4.54 gm/litre
<h3>What is the
Ideal Gas Law ?</h3>
This law combines the relationships between p, V, T and mass, and gives a number to the constant.
The ideal gas law is:
pV = nRT
where n is the number of moles, and R is universal gas constant.
The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K
The values given in the question are
p= 5.30 atm , V=3.50 L
T (in Kelvin) = 125+273 K
= 398 K
R = 0.0821 L·atm /mol·K
The Ideal Gas equation can be re written as
pM=DRT
M is the molar mass , D is the density
M for N₂ is 28 gm/mol
so density can be determined as
Therefore the density of a sample of nitrogen gas (N₂) that exerts a pressure of 5.30 atm in a 3.50-L container at 125°C is 4.54 gm/litre

Butane is
from the family of alkanes with –ane as its family name. The but- prefix stands
for having four carbon atoms. The C4H10 is the general formula of butane and
can also represent other forms or structures of butane. However if the question
asks for the molecular formula of butane, think of how many electrons it can
share to the hydrogen atom. The carbon atom can share 4 and hydrogen 1. So if the three hydrogen atoms are attached
to the first carbon, the other shared electron is attached to the second
carbon. The second carbon atom can accommodate two hydrogen and 1 carbon. The
third carbon can accommodate 2 hydrogen atoms and 1 carbon and the fourth
carbon can accommodate 3 hydrogen atoms. The molecular formula is
CH3-CH2-CH2-CH3.

Answer:
The word "Halloween" comes from All Hallows' Eve and means "hallowed evening."
Halloween's origins can be traced back to the ancient Celtic festival known as Samhain, which was held on November 1 in contemporary calendars. It was believed that on that day, the souls of the dead returned to their homes, so people dressed in costumes and lit bonfires to ward off spirits.
