What is the mass of exactly 1 mol of the following elements osmium, cesium, krypton

The mass of osmium is 190.23 g/mol, cesium is 132.9 g/mol and that of krypton is 83.8 g/mol

Explanation:

Molar mass is defined as the mass of 1 mole of an element. It is expressed in g/mol.

For the given elements:

Osmium is 76th element of the periodic table having mass of 190.23 u

Molar mass of osmium = 190.23 g/mol

Cesium is 55th element of the periodic table having mass of 132.9 u

Molar mass of cesium = 132.9 g/mol

Krypton is 36th element of the periodic table having mass of 83.8 u

Molar mass of krypton = 83.8 g/mol

Hence, the mass of osmium is 190.23 g/mol, cesium is 132.9 g/mol and that of krypton is 83.8 g/mol
