Question

Calculate the Molecular mass of phosphorus pentoxide : P2O5. Solution step by step​

Answer 1

Explanation:

first we need to take the atomic number of phosphorus and oxygen because they are the component of it so the atomic number of phosphorus is 15 and oxygen is a there are Phosphorus are to so that we are multiply 15 by 2 so we get 30 now we are multiplying 8 into 5 because 5 is the given so we get 40 now we need to add both of these 30 and 40

show the molecular mass is 70
