You can rewrite the equation to solve for mass: mass = volume x density Densityof liquids usually is expressed in units of g/ml. If you know the density of a liquid and the volume of the liquid, you can calculate its mass. Similarly, if you know the mass and volume of a liquid, y...
Find the relative mass of any atom by adding the number of protons to the number of neutrons. Hydrogen has a relative atomic mass of 1, and carbon-12 has a relative atomic mass of 12. Isotopes of the same element have different numbers of neutrons, so you need to calculate for one spe...
mass = 23.7 g In real life, you can usually look up the density of commons liquids in reference books or online. While the calculation is simple, it's important to cite answer using the correct number ofsignificant digits. Also, pay attention to the units of your answer and make sure th...

Themolecular massor molecular weight is the total mass of a compound. It is equal to the sum of the individual atomic masses of each atom in the molecule. It's easy to find themolecular massof a compound with these steps: Determine themolecular formulaof the molecule. ...
How to Find the Magnitude When Force & Angle Is Given?. When a force works in the same direction as a body moves, the entire force acts on the body. In many cases, however, the force points in a different direction. When an object slides down a slope, fo
where M is the molar mass, m is the mass of solution, and n is the number of moles. This returns a value for M in kg/mol (in SI units). This is also closely related to the molecular weight/molecular mass and the it is used to find the mass or nu...
