Question

25 mL of 3 MHNO 3 is mixed with 75 mL of 4 MHCl, the molarity of the resulting solution is (A) 2.75 M (B) 1.65 M (C) 3.75 M (D) 2.05 M

M1 V1+M2 V2=MR(V1+V2) 3 × 25+4 × 75=MR(25+75) 75+300=MR(100) MR=375 / 100 MR=3.75 M

Q. $25 m L$ of $3 M H N O_{3}$ is mixed with $75 m L$ of $4 M H Cl$ , the molarity of the resulting solution is
