Answer:
by using ideal gas law
Explanation:
ideal gas law:
PV=nRT
where:
P is pressure measured in Pascal (pa)
V is volume measured in letters (L)
n is number of moles
R is ideal gas constant
T is temperature measured in Kelvin (K)
by applying the given:
P(initial) V(initial)=nRT(initial)
P(final) V(final)=nRT(final)
nR is constant in both equations since same gas
then,
P(initial) V(initial) / T(initial) = P(final) V(final) / T(final)
then by crossing multiply both equations
V (final)= { (P(initial) V(initial) / T(initial)) T(final) } /P (final)
P(initial)=P(final)= 1 atm = 101325 pa
V(initial)= 6 L
T(initial) = 28°c = 28+273 kelvin
T(final) = 39°c = 39+273 kelvin
by substitution
V(final) = 6.21926 L
Answer:
What can liquids do that solids cannot?Liquids will flow and fill up any shape of container. Solids like to hold their shape. In the same way that a large solid holds its shape, the atoms inside of a solid are not allowed to move around too much. Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want.
What can gases do that solids cannot?The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

The mass of carbon monoxide present in the room is 0.006502 g.
<h3>What is Density?</h3>
Density is the mass of a substance per unit volume.
Where
ρ = density of the substance
m = mass of the substance and
V = volume of the substance
Here, ρ = 48 μg/m³
Volume = 13 ft x 13.5 ft x 19.5 ft
1 ft = 0.3408 m
V = (13 x 0.3408 m) x (13.5 x 0.3408 m) x (19.5 x 0.3408 m)
= 135.46 m³
m = ρ x V
= 48 μg/m³ x 135.46 m³
= 6502.08 μg
= 6502.08 x 10⁻⁶ g
=0.006502g
Hence, The mass of carbon monoxide present in the room is 0.006502 g.
