using the periodic table, find the molar mass of diphosphorus pentoxide (p₂o₅). write your answer to the hundredths place. round if necessary. g/mol

Answer

Explanation:

Step1: Find P molar mass

The molar mass of phosphorus (P) from the periodic - table is approximately 30.97 g/mol. In $P_2O_5$, there are 2 P atoms. $2\times30.97 = 61.94$ g/mol

Step2: Find O molar mass

The molar mass of oxygen (O) from the periodic - table is approximately 16.00 g/mol. In $P_2O_5$, there are 5 O atoms. $5\times16.00=80.00$ g/mol

Step3: Calculate molar mass of $P_2O_5$

Add the molar masses of P and O in $P_2O_5$. $61.94 + 80.00=141.94$ g/mol

Answer:

141.94 g/mol
