Rather than work with mass of single atom, scientist prefer to work with molar masses which is the mass of a very large number of atoms called the mole. A mole of any element contains 602,000,000,000,000,000,000,000 or 6.02x10²³atoms. <div class="sign-up-notice-after-excerpt-two" style="background-color:powderblue;"> You are viewing an excerpt of this lesson.
