What is the mass of 2.25 moles of manganese(lv) sulfide(mns2)

Explanation:

Number of moles is defined as mass divided by molar mass of the substance or atom.

Mathematically,     No. of moles =

It is known that molar mass of is 119.058 g/mol and number of moles is given as 2.25 mol.

Therefore, calculate mass of as follows.

                          No. of moles =

                                   2.25 mol =

                                 mass = 267.88 g

Thus, we can conclude that mass of 2.25 moles of manganese(lv) sulfide(MnS2) is 267.88 g.
