OneClass: What is the molar mass of phosphorus?
Calculate the molar mass of HNO3. Ask questions, doubts, problems and we will help you.
The key difference between molar mass and molecular mass is that the molar mass gives the average mass of the molecule whereas the molecular mass gives the mass of a single molecule. Atoms can join together in various combinations to form molecules and other compounds. Molecular structures give the exact ratios of atoms; thus, we can write molecular formulas for compounds.
Q. The volume of an aqueous solution is 1.50L. It contains 12.5g of NaCl. What is the molarity of the solution?
Molar mass, sometimes referred to as molecular weight, is the mass of one mole of a substance, and is usually expressed in A Liters B Grams C Density D Moles D? The mole is derived from the quantity of atoms in 12 grams of carbon-12. The mole is just a number, it can be used for: A Molecules B Atoms C Ions D All of the above D? Calculate the molecular mass of calcium chloride (CaCl 2 ). A 35.
