Molarity is a concentration unit, defined to be the number of moles of solute divided by the number of liters of solution.
Chemistry affects all aspects of life and most natural events because all living and nonliving things are made of matter.
Atomic mass Calcium ( Ca) = 40.078 u.m.a
40.078 g --------------- 6.02x10²³ atoms
187 g ------------------- ??
187 x ( 6.02x10²³) / 40.078 =
1.125x10²⁶ / 40.078 = 2.808x10²⁴ atoms
