# how many atoms are in 3o2

Answer and Explanation: To calculate how many atoms of each element there are, we multiply the coefficients by the subscripts. For example, in 3O2 3 O 2 , the three is a coefficient and the 2 is a subscript. The total number of oxygen atoms would therefore be 3×2=6 3 × 2 = 6 . ## How many oxygen atoms are in 3O2?
