The atomic mass of nitrogen is 14.01, hydrogen is 1.01, sulfur is 32.07, and oxygen is 16.00. what is the molar mass of ammonium sulphate [(nh4)2so4]?

Molar mass is the mass of 1 mole of substance

Molar mass of a compound is the sum of the products of the atomic masses of the elements by the number of atoms of each element

we can use the following equation

molar mass of (NH₄)₂SO₄ = 2 (atomic mass of N + 4(atomic mass of H)) + atomic mass of S + 4(atomic mass of O)

atomic masses of the elements are as follows

N - 14.01

H - 1.01

S - 32.07

O - 16.00

substituting these values

molar mass of (NH₄)₂SO₄ = 2 (14.01 + 4(1.01) + 32.07 + 4(16.00)

molar mass of (NH₄)₂SO₄ = 2 (14.01 + 4.04) + 32.07 + 64.00 = 2 (18.05) + 32.07 + 64.00

molar mass of (NH₄)₂SO₄ = 36.1 + 32.07 + 64.00 = 132.17

molar mass of (NH₄)₂SO₄ is 132.17 g/mol

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

the answer is b. dilution
