![The reaction occurs according to the following equation:
H2SO4 + 2KOH -> 2H20 + K2SO4
How do you find the number of moles of H2SO4? Are all parameters needed to
answer the question known? If not, which one should be determined next?
#mol of target molecule (H2SO4) = mole ratio of (target / known molecule
(KOH)) / #mol of known molecule. The mole ratio is known (1/1), but not the
#mol of KOH, which should be determined next.
O #mol of target molecule (H2SO4) = mole ratio of (target/ known molecule
(KOH)) x #mol of known molecule. The #mol of KOH (2 mol) and its mole ratio
are both known.
O #mol of target molecule (H2SO4) = mole ratio of (target / known molecule
(KOH)) x #mol of known molecule. The mole ratio is known (1/2), but not the
#mol of KOH, which should be determined next.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbe59f415-ff28-496e-9b98-27df6965f5b1%2F696e1155-8767-45c1-a45c-6f30876f6740%2Fnkpbb0v_processed.jpeg&w=3840&q=75)
