Correct Answer

A. 10 पीपीएम / 10 ppm

Step 1

Concept

For dilute aqueous solutions, 1 kg water is about one million mg.

Step 2

Why this answer is correct

10 mg per one million mg = 10 ppm.

Step 3

Exam Tip

In water, mg per kg can often be read as ppm. चरण 1: जल जैसे पतले विलयन में 1 किलोग्राम लगभग 10 लाख मिलीग्राम माना जा सकता है। चरण 2: 10 मिलीग्राम प्रति 10 लाख मिलीग्राम = 10 पीपीएम। चरण 3: जल में मिलीग्राम प्रति किलोग्राम को अक्सर पीपीएम के रूप में पढ़ सकते हैं।
