Question

Molest mass of HC104​

Answer 1

Answer:

1+12×104

Explanation:

12+1248

1260

Answer 2

Answer:

100.46 gm/mol

Explanation:

In order to determine the molecular weight, we need to refer to a periodic table to find the values of the relative atomic masses of the elements in the compound.

Relative atomic mass of H=1.01

Relative atomic mass of Cl=35.45

Relative atomic mass of O=16.00

So, molar mass of HClO4 = (1.01 + 35.45 + 4 × 16.00)gm/mol = (36.46 + 64.00 ) = gm/mol = 100.46 gm/ mol

I hope you get the answer.
