HOW TO GET percent of magnesium by mass?
To calculate the percentage of magnesium by mass in a compound, divide the mass of magnesium by the total mass of the compound, then multiply by 100. Percentage of magnesium by mass = (mass of magnesium / total mass of compound) * 100.
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
Is atomic mass and molar mass similar and mass number of particles the same?
Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.
What does gacrux mean?
Gacrux is the traditional name for the star Gamma Crucis in the constellation of Crux (the Southern Cross) in the southern sky. The name is derived from a combination of the star's constellation (Crux) and its Bayer designation (Gamma).
What is the temp of gacrux?
Gacrux, also known as Gamma Crucis, is a red giant star located in the constellation Crux. Its surface temperature is approximately 3,800 Kelvin. This cooler temperature contributes to its reddish appearance, distinguishing it from hotter, blue or white stars.
What color is Gamma Crucis?
Gamma Crucis (Gacrux) has a spectral type of M3.It therefore has a colour of red.It is also the nearest red giant to us.

How far is a red giant from earth?
The closest red giant to Earth is a star named Gacrux (also called Gamma Crucis). It is 88 light years away from us and can be seen in the constellation of the Southern Cross.
Name of the 5 stars on the southern cross?
Alpha Crucis, Beta Crucis, Delta Crucis, Gamma Crucis, and Epsilon Crucis,
How is mass different from mass?
Mass and mass are the same thing.
How do you find a mass by difference?
Mass of the contained material = Total mass (mass of the container + mass of the material) - Mass of container
What is the formula for mass percent?
mass % of element X = mass of element X ____________________ X 100 total mass of compound or mass of solute _____________________________ X 100 mass of solute + mass of solvent
Does mass have mass?
Yes, mass has mass. It is, therefore, matter. If mass did not have mass, then it is "something" with no mass. That would make it "non-matter" and perhaps it might be energy.
