Concept explainers
(a)
Interpretation:
The number of moles should be calculated present in 100.0 g of dinitrogen oxide.
Concept introduction:
Number of moles of a compound is defined as the ratio of given mass of the compound to the molar or molecular mass of the compound.
The mathematical expression is given by:
Number of moles =
The one mole of any substance is equal to the
Answer to Problem 133A
Number of moles of dinitrogen oxide =
Explanation of Solution
Mass of dinitrogen oxide = 100.0 g
Molar mass of dinitrogen oxide = 44.013 g/mole
Number of moles =
Number of moles of dinitrogen oxide =
