The andromeda galaxy is approximately 1.5 x 1012 solar mass. based on the passage, what is likely true about the andromeda galaxy?

most of the galaxy’s mass is probably made up of dark matter.

over 1 x 1012 mass is probably made up of stars.

over half the galaxy’s mass is probably made up of gas and dust.

the galaxy’s mass is composed of stars, gas, and dust.

the fossil record provides evidence of a common ancestor to many species.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
