Answer:

Antimony

Step-by-step explanation:

Number of moles = 9.51 mol

Mass= 1157.9376 g

The identity of an element is obtained from it's Molar mass.

This is given by the equation;

Molar mass = Mass / Number of moles

Molar mass = 1157.9376 g / 9.51 mol

Molar mass = 121.76

The only element with molar mass of 121.76 is Antimony
