How many total of atoms are in 0.370gr of P2O5
Irina-Kira [14]
142 g ---------------- 6.02 x 10²³ molecules
0.920g g ------------ ( molecules )

molecules = 0.920 x ( 6.02 x 10²³ ) / 142

molecules = 5.53 x 10²³ / 142

= 3.89 x 10²¹ molecules

1 molecule P2O5 -------------------------- 7 atoms
3.89 x 10²¹ molecules -------------------- ( atoms )

atoms = ( 3.89 x 10²¹) x 7 / 1

atoms = <span>2.72 x 10²² atoms of P2O5


 Hope this helps!!!

Part A Which of the following statements about chemical formulas is FALSE? Which of the following statements about chemical form
statuscvo [17]

Answer: Option (a) is the correct answer.

Explanation:

Subscript present in chemical formula of a compound represents the number of atoms of the element actually present in it.  

For example, in C_{7}H_{7}NO_{2} the subscripts present in it are 7, 7, 1, and 2.

A subscript is not responsible for determining the relative mass of each type of an atom because a subscript simply represents the number of atoms of each type of an element participating or combining with other atoms of a compound.

Thus, we can conclude that the statement subscripts represent the relative mass of each type of atom in the compound, is false.
