Frequently Asked Questions
What is molarity?
Molarity (M) is a measure of concentration that represents the number of moles of solute per liter of solution. It's one of the most common ways to express solution concentration in chemistry.
How do you calculate molarity?
Molarity is calculated by dividing the number of moles of solute by the volume of solution in liters. The formula is: M = n / V, where M is molarity, n is moles, and V is volume in liters.
What's the difference between molarity and molality?
Molarity (M) is moles of solute per liter of solution, while molality (m) is moles of solute per kilogram of solvent. Molarity changes with temperature because volume changes, but molality doesn't.
How do you convert molarity to moles?
To convert molarity to moles, multiply the molarity by the volume in liters: moles = M × V. For example, a 2 M solution with 0.5 L volume contains 1 mole of solute.
What is a 1 M solution?
A 1 M (one molar) solution contains exactly 1 mole of solute dissolved in enough solvent to make 1 liter of total solution. For example, 1 M NaCl contains 58.44 grams of sodium chloride per liter.
Can molarity be greater than 1?
Yes, molarity can be any positive number. Concentrated solutions like concentrated HCl can be 12 M or higher. There's no upper limit, though very high concentrations may exceed the solubility limit of the solute.
