An object has a volume of 2 milliliters and a mass of 10 grams, calculate the density of the object

Nickel crystallizes in the face-centered cubic (fcc) lattice. the density of the metal is 8902 kg/m3. calculate the radius of a nickel atom.

When determining the shape of a molecule, it is important to draw a lewis dot structure first in order to see the total number a. electrons within the moleculeb. bonding and unshared pairs around central atomc. unshared pair within the molecule( i really need it )

Exit what is the density of an object having a mass of 5.0 g and a volume of 45.0 cm3?
