What is the molar mass of MgI2

278.1g/mol

Explanation:

To find the molar mass of the given compound, we must know the atomic mass of the elements within the compound.

Atomic mass of Mg = 24.3g/mol

Atomic mass of I  = 126.9g/mol

So;

  Molar mass  = 24.3 + 2(126.9) = 278.1g/mol

The molar mass of the compound is  278.1g/mol

answer: they produce more slow than unicellular organisms.
