Calculate the molar mass for Cr2(SO3)3. Be sure to include units.

Number:

Units:

344.21 g/mol

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

Cr₂(SO₃)₃

Step 2: Identify

Molar Mass of Cr - 52.00 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Step 3: Find

Molar Mass of Cr₂(SO₃)₃ - 2(52.00) + 3(32.07) + 9(16.00) = 344.21 g/mol

put the answers   and i could answer.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
