According to the balanced equation, 2 moles of HCl react with 1 mole of Ba(OH)2 to produce 1 mole of BaCl2 and 2 moles of H2O.
Therefore, to determine how many moles of HCl are needed to react with 0.0500 mol of Ba(OH)2, we need to use the mole ratio:
2 mol HCl / 1 mol Ba(OH)2
So:
0.0500 mol Ba(OH)2 x (2 mol HCl / 1 mol Ba(OH)2) = 0.100 mol HCl
Therefore, 0.100 mol of HCl are needed to react with 0.0500 mol of Ba(OH)2.
For the following reaction, Given 0.0500 mol of Ba(OH)2, how many moles of HCI are needed using balanced equation below?
2 HCI (aq) + Ba(OH)2 (aq)
