Water is an excellent solvent, salt is carried by the water due to erosion and carried to the ocean.
Answer : The correct expression is, (150 × 3 × 31.998) ÷ (232.29 × 1) grams
Explanation :
First we have to calculate the moles of 

Now we have to calculate the moles of 
The balanced chemical reaction is,

From the balanced chemical reaction we conclude that,
As, 1 mole of
react to give 3 mole of 
So,
moles of
react to give
moles of 
Now we have to calculate the mass of 


Therefore, the correct expression for the mass of oxygen gas formed is, (150 × 3 × 31.998) ÷ (232.29 × 1) grams
Answer:
<h2>8.92 g/cm³</h2>
