Chapter 10.3, Problem 50SSC

Interpretation Introduction

Interpretation:

The number of moles of K, C and O needs to be determined.

Concept introduction:

If number of mole of a compound is given and molecular formula of the compound is given thus, the number of moles of atoms can be calculated from unitary method.

Answer to Problem 50SSC

$2\text{ moles }\text{'}K\text{'},2\text{ moles }\text{'}C\text{'},4\text{ moles }\text{'}O\text{'}.$

Explanation of Solution

Given information:

$1\text{ mole }{K}_2{C}_2{O}_4.$

Calculation :

For $1$ mole of $K_2{C}_2{O}_4.$

$\to$ It has $\begin{array}{l}2\text{ moles }\text{'}K\text{'}\\ 2\text{ moles }\text{'}C\text{'}\\ 4\text{ moles }\text{'}O\text{'}.\end{array}$

Conclusion

The number of moles of K, C and O is 2, 2 and 4 respectively.
