The atomic planes in a graphite Crystal are separated by 335pm. At what angle would you find the first order (n=1) diffraction of 0.154-no X rays from graphite crystal?

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid
