density = mass / volume Solving for mass: mass = density x volume Solving for volume: volume = mass / density
reg.% by mass mass% m/m mass of solute mass of solution=x100
density = mass / volume
Mass = Density x Volume Density = Mass ÷ Volume Volume = Mass ÷ Density

to solve vibration problems
I am not sure what problem you are trying to solve, but I assume you have to add the masses.
to solve for mass u divide force by acceleration . to find force u multiply mass and acceleration and to find acceleration u divide force by mass , force is measured in newtons (N) and mass is measured in meters per second squared ( m/s^2) and acceleration is measured in kilograms ( kg) .
force equals mass times acceleration
Volume D=m/v
You find the volume of the object, and then divide it by the mass.
Subtract the atomic number from the mass number
