<span>The answer is: C. The amount of water in the hydrosphere remains constant. 

</span>The hydrosphere denotes the entire water available worldwide in lakes and streams, subsurface water, the ice of glaciers, and water vapor in the atmosphere. The water cycle is the process that converts liquid water to atmospheric water vapor (and vice versa) throughout the world.

A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solutio
Alja [10]

Answer:

Concentration of original solution = 1.66

Explanation:

We know that

H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O

We have given concentration of NaOH = 0.1678

Volume of NaOH = 19.88 mL = 0.01988 L

So moles of NaOH = volume x concentration of NaOH

= 0.01988\times 0.1678=0.00333mole

Moles of H_2SO_4 in 10 mL of diluted solution = 1/2 x moles of NaOH

= \frac{1}{2} x 0.00333 = 0.00166 mol

Moles of H_2SO_4 in 25 mL of original solution

= moles of H2SO4 in 250 mL of diluted solution

= \frac{250}{10} x 0.00166 = 0.0415 mol

Concentration of original solution = \frac{moles}{volume}

= \frac{0.0415}{0.025}=1.66
