To do this, start by dividing the smallest number of moles into each of the numbers of moles of elements (i.e., set the smallest number to 1). This may yield integers, or it may yield decimal results that correspond closely to rational fractions. For example, 1.25: 2.75 = 1¼: 2¾ = 5: 11 1.25: 2.75 = 1 ¼: 2 ¾ = 5: 11. unit chemical quantities molar mass 2-Step worksheet 3. 8 terms. jujuuondatbeattt. Preview. The Mole. Teacher 25 terms.
