Answer:

21121.58 grams

Step-by-step explanation:

Given, 9.96 times 10 to the power of 26 atoms of tellurium

Convert atoms into moles of tellurium,

As we know, 1 mol= 6.02 *10 to the power of 23 atoms

Hence, 9.96 *10 to the power of 26/ 6.02 *10 to the power of 23= 1654 moles of tellurium

Now, mass= molar mass*moles

As we know, tellurium has a molar mass of 127.6000 g/mol

Mass= 1654 *1277 g/mol

= 21121.58
