Which solution is the most concentrated? 2.0 ml of 10 m h2so4, where h2so4 has a molar mass of 98 g/mol5.0 ml of 1.0 m pbso4, where pbso4 has a molar mass of 303 g/mol2.0 ml of 10.5 m h2o2, where h2o2 has a molar mass of 34 g/mol100 ml of 10 m nacl, where nacl has a molar mass of 58 g/mol

2.0 ml of 10 m is the most concentrated solution with 0.98 g of sulfuric acid present in unit milliliter of the solution.

Explanation:

1. 2.0 ml of 10 M ,

x = 1.96 g

Mass present in 1 ml of the solution =

2. 5.0 ml of 1.0 M

x = 1.515 g

Mass present in 1 ml of solution =

3. 2.0 ml of 10.5 M [tex[H_2O_2[/tex]

x = 0.714 g

Mass present in 1 ml of solution =

4. 100 ml of 10 M NaCl

x = 58 g

Mass present in 1 ml of solution =

2.0 ml of 10 m is the most concentrated solution with 0.98 g of sulfuric acid present in unit milli liter of the solution.
