JEE Main 2024 Chemistry question
Consider the following reaction: 3PbCl + 2(NH)PO → Pb(PO) + 6NHCl. If 72 mmol of PbCl is mixed with 50 mmol of (NH)PO, then the amount of Pb(PO) formed is mmol (nearest integer).
Answer: 24
Solution
PbCl is limiting (72/3 = 24 versus 50/2 = 25), so 24 mmol of Pb(PO) forms.
