BF3 acts as a Lewis acid when it accepts the lone pair of electrons that NH3 donates.
The mass of water in the tank, given the data from the question is 549594 g
<h3> Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
<h3>How to determine the mass of water in the tank</h3>
From the question given above, the following data were obtained:
- Mole of water = 30533 moles
- Molar mass of water = 18 g/mol
- Mass of water = ?
The mass of the water can be obtained as follow:
Mass = mole × molar mass
Mass of water = 30533 × 18
Mass of water = 549594 g

Answer:
- <u><em>Option A.) 2 ppm</em></u>
Explanation:
<u><em>60 particles in 30 million</em></u> can be expressed as a fraction:
And, dividing both numerator and denominator by 30, that can be simplified as:
That means 2 particles of sulfur dioxide in 1 million particles of sample, which is 2 parts per million or<u> 2 ppm</u>, which is the option A.
