Asolution of h 2 so 4 ( aq ) with a molal concentration of 1.66 m has a density of 1.104 g / ml . what is the molar concentration of this solution?

1.58 M

Explanation:

is 1.66 m concentration.

Which means that 1.66 moles of   are present in 1 kg of the solvent, water.

Mass of water = 1 kg = 1000 g

Moles of = 1.66 moles

Molar mass of = 98.079 g/mol

The formula for the calculation of moles is shown below:

Thus,

Total mass = 1000 g + 162.81114 g = 1162.81114 g

Density = 1.104 g/mL

Volume of the solution = Mass / Density = 1162.81114 / 1.104 mL = 1053.27 mL = 1.05327 L

Considering:-

Molarity = moles/ Volume of solution = 1.66 / 1.05327 M = 1.58 M

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
