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.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
