Concept explainers
Interpretation:
The mole ratio that can convert moles of A to moles of B should be determined.
Concept introduction:
The ratio of mass of substance to its molar mass is said to be number of moles of that substance.
The ratio of amount of any two compounds involved in a

Answer to Problem 39A
The mole ratio that can convert moles of A to moles of B is:
Explanation of Solution
The mole ratio is determined from the balanced chemical equation that is from the coefficients of a balanced chemical equation.
Now, to convert moles of A to moles of B their coefficients in balanced chemical equations are determined first. Let the coefficient of A be a and coefficient of B be b. then the mole ratio of A and B will be a:b which can be written as:
This can be rewritten as the ratio of mol of B to A as:
Hence, the mole ratio that can convert moles of A to moles of B is:
