#1: martha has a large amount of 1.25 m h2so4 in her lab. she needs 36 grams of h2so4 for a chemical reaction she wants to perform. how many liters of the solution should she use? a. 2.9 l b. 5.8 l c. 0.58 l d. 0.29 l ***my d. 0.29 l is that right? @chmvijay : ),

D. 0.29 L

Explanation:

To calculate the required volume, we can convert the concentration of the solution from M to g/L, keeping in mind the molar mass of H₂SO₄, 98 g/mol :

1.25 122.5 g/L

So a concentration of 1.25 M of H₂SO₄ is the same as a concentration of 122.5 g/L.

Finally we divide 36 grams by the concentration:

= 0.29 L

So your answer was correct, it is option D.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

the answer to your question is c
