Explanation:
This is expressing as a subject of a formula of a specie.
This equation is used in solving for specific heat capacity of a material;
equation:
c =
First cross multiply:
c[M(T2 - T1)] = h
Then multiply both sides by :
x c[M(T2 - T1)] =
x h
M(T2 - T1) =
Multiply both sides by
x M(T2 - T1) =
T2 - T1 =
Now rearrange to produce;
T1 = T2 +

1.905 moles of Helium gas are in the tube. Hence, option A is correct.
<h3>What is an ideal gas equation?</h3>The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
Calculate the moles of the gas using the gas law,
PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.
Given data:
P= 4.972 atm
V= 9.583 L
n=?
R=
T=31.8 +273= 304.8 K
Putting value in the given equation:
=n
n=
Moles = 1.905 moles
1.905 moles of Helium gas are in the tube. Hence, option A is correct.
