0.753 M MgCl2 is the molarity of a solution prepared from 19.7 grams of mgcl2 in 275 milliliters of solutions
What is molarity ?
Molar concentration, also known as molarity, quantity concentration, or substance concentration, is a unit used to describe the amount of a substance in a solution expressed as a percentage of its volume. The number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units, is the most often used unit denoting molarity in chemistry.
One mol/L of a solution's concentration is referred to as one molar, or 1 M. Because the volume of most solutions very minimally changes with temperature owing to thermal expansion, using molar concentration in thermodynamics is frequently not practical. Usually, incorporating temperature adjustment factors or utilizing a temperature-independent metric will fix this issue.
