Mass of PVC used is $\underset{\_}{384\times {10}^6\text{ kg}}$ .

Explanation of Solution

Given:

Total amount of PVC used = $6,400,000,000\text{ kg}$

Amount of PVC used in packaging = $\text{6\%}$

Calculation:

Mass of PVC used in packaging is calculated as:

  $\begin{array}{l}\text{ 6\% of 6,400,000,000 kg}\\ \text{=}\frac{6}{100}\text{ of 6,400,000,000}\\ \text{= 384000000}\text{kg}\\ =384\times {10}^6\text{ kg}\end{array}$

Conclusion:

Mass of PVC used is $\underset{\_}{384\times {10}^6\text{ kg}}$ .
