a. the number of molecules
b. average molecular speed
c. the number of atoms
d. a and c
Please explain why or why not the answer is d. If the moles of a gas is constant, would not the number of molecules and atoms be the same? Also, please explain why b is incorrect.

Sagot :

Equal volumes of propane, C₃H₈, and carbon monoxide, CO, at the same temperature a) the number of molecules.

a) the number of molecules are same this is true. the ideal gas equation is given as :

P V = n R T

n = P V / R T

a mole of gas contains Avogadro's number of molecules . so, the number of molecules are equal.

b) average molecular speed is depends on the molar mass and the have different molar mass. so, this statement is not true.

c) the no. of atoms are same is also not true. because the propane contains 11 atoms per molecule and the carbon monoxide contains the only two atoms.
