Answer:
Option A is correct.
Explanation:
Given data:
Mass of ammonia = 1.6 g
Volume of water = 147 mL
Concentration in ppm = ?
Solution:
As we know that,
1 g/mL = 1000000 ppm
1.6 g/147 mL = 0.011 g/mL
Now we will convert the 0.011 g/mL into ppm.
0.011 × 1000000 = 11000 ppm
In scientific notation:
1.1×10⁴ ppm
Thus, option A is correct.
