Asolution of so2 in water contains 0.00023 g of so2 per liter of solution. what is the concentration of so2 in ppm? in ppb?

= 230 ppb

Explanation:

Considering that;

1ppm = 1mg/L  

Then;

0.00023g = 0.23mg  

Therefore;

0.00023 g/L = 0.23 mg/L

0.23 mg/L = 0.23 ppm

1 ppm = 100 ppb

Therefore;

0.23 ppm = 0.23 ×1000

                = 230 ppb

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
