Question
Zirconium (Zr) is a metal used in nuclear reactors because
it is resistant to corrosion. What is the mass of a sample
that contains 4.05 mol of zirconium?



Answer :

GinnyAnswer
To find the mass of a sample containing 4.05 mol of zirconium (Zr), we need to use the molar mass of zirconium to convert moles to grams. 1. Determine the molar mass of zirconium (Zr) from the periodic table. The atomic mass of zirconium is approximately 91.22 g/mol. 2. Use the given number of moles (4.05 mol) and multiply it by the molar mass of zirconium: 4.05 mol Zr * 91.22 g/mol = 369.201 g 3. Therefore, the mass of a sample containing 4.05 mol of zirconium is approximately 369.201 grams.
