What is the mass of KNO3?
Question:
What is the mass of KNO3?
Potassium and Nitrate:
KNO3 is an ionic compound named potassium nitrate. The potassium ion has a -1 charge, and the nitrate ion has a -1 charge. Since their charges add up to zero, they combine in a 1:1 ratio.
Answer and Explanation:
The molar mass of KNO3 is 101.1032 g/mol.
All we have to do to determine the molar mass of this compound is to add up the molar masses of each element in the compound. Since there are three oxygen atoms, we need to multiply oxygen's molar mass by ''3'' before we sum all of the values.
Potassium's molar mass is 39.0983 g/mol.
Nitrogen's molar mass is 14.0067 g/mol.
Three oxygen atoms' molar mass is (3)(15.9994 g/mol) = 47.9982 g/mol.
Summing these values gives us:
39.0983 g/mol + 14.0067 g/mol + 47.9982 g/mol = 101.1032 g/mol
