What is the molarity of a solution prepared by dissolving 1.25g of HCl gas into enough water to make 30cm3 of solution

The molarity of a solution : 1.13 M

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

Where

M = Molarity

n = Number of moles of solute

V = Volume of solution

mass HCl = 1.25 g

mol HCl(MW=36.5 g/mol) :

Volume of solution = 30 cm³ = 0.03 L

The molarity :

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
