Rank the following in order of increasing molar mass: H2O2, I2, LiF, CH6N. A. I2< LiF < H2O2 < CH6N
B. LiF < CH6N C. H2O2 < LiF < I2 < CH6N
D. CH6N < H2O2 < I2 < LiF

B.  LiF < CH6N < H2O2 <I2

Explanation:

Find the molar mass of LiF

To do that, first look at the atomic mass of each element on the periodic table.

But they are one lithium atom and one fluorine atom

So you use this equation:

LiF has 25.9 g/mol

Now find the molar mass of CH6N.

To do that, first look at the atomic mass of each element on the periodic table.

But they are six hydrogen atoms, one carbon atom, and one nitrogen atom.

So you use this equation:

CH6N has 32 g/mol

Now find the molar mas of H2O2

To do that, first look at the atomic mass of each element on the periodic table.

But they are two oxygen atoms and two hydrogen atoms.

So you use this equation:

H2O2 has 34 g/mol.

Lastly, find the molar mass of I2

To do that, first look at the atomic mass of each element on the periodic table.

But they are two iodine atoms.

So you use this equation:

I2 has 253.8 g/mol

Now that we calculated the molar mass of all elements. We rank it in the following of increasing atomic mass.

Therefore, the final answer is B.  LiF < CH6N < H2O2 <I2
