Question

Which solution is the most concentrated?
A.2.0 mL of 10 M H2SO4, where H2SO4 has a molar mass of 98 g/mol
B.5.0 mL of 1.0 M PbSO4, where PbSO4 has a molar mass of 303 g/mol
C.2.0 mL of 10.5 M H2O2, where H2O2 has a molar mass of 34 g/mol
D.100 mL of 10 M NaCl, where NaCl has a molar mass of 58 g/mol

Answer 1

A
what do you say @Abmon98

Answer 2

B & D is definitely incorrect

Answer 3

H2SO4 is diprotic..

Answer 4

you are correct :D

Answer 5

Okay, thanks for the confirmation

Answer 6

your most welcome :)

Answer 7

The most concentrated solution is the one with the highest molarity. In this case answer C. has the highest molarity, so it is the most concentrated.
