Answer:
38,050,000,000,000 picoliters.
Explanation:
10-5=5, 7.61 x 5=38.05 (38.05L)
every liter is equal to 1000000000000 picoliters, so you go from there and just multiply 1000000000000 by 38.05.
Here N H 4 O H { NH }_{ 4 }OH NH4OH is not a strong electrolyte because it doesn't dissociates completely.
