Solution
Correct Answer:
0.2 M
Molarity (M) = Volume of solution (L)moles of solute
- Find Moles of H2SO4:
- Molar mass =2(1)+32+4(16)=98 g/mol.
- Moles=9.8/98=0.1 mol.
- Find Molarity:
- Volume =500 mL=0.5 L.
- M=0.1/0.5=0.2 M.
This easy difficulty chemistry question is from the chapter some basic concepts in chemistry, covering the topic of molarity and molality. It appeared in the 2025 exam.
