Question

How do you find how many atoms are found in the chemical formula H2O?

a) Count the number of elements
b) Multiply the subscripts
c) Divide by the atomic weight of hydrogen
d) Add the atomic weights of hydrogen and oxygen

Answer 1

To find the number of atoms in the chemical formula H2O, can be determined by multiplying the subscripts of each element in the formula. In H2O, there are 2 hydrogen atoms and 1 oxygen atom multiply the subscripts of each element. There are 4 hydrogen atoms and 1 oxygen atom in H2O.

Step-by-step explanation:

The number of atoms in the chemical formula H2O can be determined by multiplying the subscripts of each element in the formula. In H2O, there are 2 hydrogen atoms and 1 oxygen atom. Multiplying the subscripts, 2x2=4 hydrogen atoms and 1x1=1 oxygen atom. So, in total, there are 4 hydrogen atoms and 1 oxygen atom in H2O.

number of atoms in the chemical formula H2O, can be determined by multiplying the subscripts of each element in the formula. In H2O, there are 2 hydrogen atoms and 1 oxygen atom multiply the subscripts of each element. There are 4 hydrogen atoms and 1 oxygen atom in H2O.
