To find the total number of atoms in Li2SO4, we first need to identify the number of each atom in the compound:
Li2SO4
There are 2 Li (lithium) atoms.
There is 1 S (sulfur) atom.
There are 4 O (oxygen) atoms.
Now, we add up the total number of atoms:
2 Li + 1 S + 4 O = 7 total atoms
Therefore, the correct answer is g. 7 total atoms.
For each compound below, count the TOTAL number of atoms.
Remember:
the subscripts tell you how many of each atom are in the compound. If there is NO subscript, it is understood to be 1.
a chemical symbol will have 1 or 2 letters. The first letter is always uppercase, and the second letter will be lower case.
if a polyatomic ion is in parentheses, the number outside the parentheses will distribute to all atoms inside the parentheses. For example: In the compound, Fe2(CO3)3 - There are 2 Fe atoms, 3 (3x1) C atoms, and 9 O (3 x 3) atoms.
