That depends on what the question is. A percent is just a number. You're asking "How do you solve a number?"
Yes, mass percent and percent by mass are the same concept. Both terms refer to the percentage of a component in a mixture by mass.
You should solve for an empirical formula when you are given the percent composition of elements in a compound or when you have the molar mass of the compound but not the molecular formula. The empirical formula provides the simplest whole-number ratio of atoms in a compound.
15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.
166.6/100
percent concentration = (mass of solute/volume of solution) X 100 To solve for mass of solute, mass of solute = (percent concentration X volume of solution)/100 So, mass of solute = (10% X 100mL)/100 = 10g
density = mass / volume Solving for mass: mass = density x volume Solving for volume: volume = mass / density
multiply by acceleration
Percent composition is usually expressed as a percent by mass, but in the case of gases and vapors, it is often expressed as a percent by volume.
Percent by mass = (100) times (mass of the ingredient of interest) divided by (mass of the whole mixture)
The mass percent of oxygen is approximately 21% in Earth's atmosphere.
A percent is simply a proportion out of 100.
