What is the molecular formula of a compound with the empirical formula so and molecular weight 96.13?

garik1379 [7]

<h3>Answer:</h3>

Molecular Formula = S₂O₂ (Disulfur Dioxide)

<h3>Solution:</h3>

Molecular formula is calculated by using following formula,

Molecular Formula = n × Empirical Formula ---- (1)

Also, n is given as,

n = Molecular Weight / Empirical Formula Weight

Molecular Weight = 96.13 g.mol⁻¹

Empirical Formula Weight = 32.06 (S) + 16.0 (O) = 48.06 g.mol⁻¹

So,

n = 96.13 g.mol⁻¹ ÷ 48.06 g.mol⁻¹

n = 2.0002 ≈ 2

Putting Empirical Formula and value of "n" in equation 1,

Molecular Formula = 2 × SO

Molecular Formula = S₂O₂ (Disulfur Dioxide)

Which element has a 4s sublevel with 2 electrons for its outermost electrons.

Papessa [141]

Answer:

Calcium

Explanation:

Hi!

So, the best way to solve this is with a period table with all of the sublevels labeled. (check below)

So the s sublevel starts at 1s which is Hydrogen. If you go down 4 rows, or periods, you get to sublevels 4s. As you should know, as you go across groups/columns, the valence electrons get higher. So the element that you are looking for has 2 valence electrons. So, the element you are looking for should be 4 down and 1 right of Hydrogen which is: Calcium

I hope I helped and have a wonderful evening!

Initial mass of triphenyl methanol in g = 0.220g Initial volume of 33% HBr solution in ml = 0.60 ml Find mas of triphenyl bromid

tensa zangetsu [6.8K]

Answer:

0.792g of triphenyl bromide are produced.

Explanation:

The reaction of triphenyl methanol with HBr is:

triphenyl methanol + HBr → Triphenyl bromide.

<em>Reaction (1:1), 1 mole of HBr reacts per mole of triphenyl methanol.</em>

<em />

To know the mass of triphenyl bromide assuming a theoretical yield (Yield 100%) we need to find first <em>limiting reactant</em>:

Moles triphenyl methanol (Molar mass: 260.33g/mol) =

0.220g × (1mol / 260.33g) = <em>8.45x10⁻³ moles Triphenyl methanol</em>

Moles HBr (Molar mass: 80.91g/mol; 33%=33g HBr/100mL) =

0.60mL ₓ (33g / 100mL) ₓ (1mol / 80.91g) = <em>2.45x10⁻³ moles HBr</em>

<em />

As amount of moles of HBr is lower than moles of triphenyl methanol, HBr is <em>limiting reactant.</em>

<em />

As HBr is limiting reactant, moles produced of triphenyl bromide = moles HBr = <em>2.45x10⁻³ moles</em>

As molar mass of triphenyl bromide is 323.2g/mol, mass of triphenyl bromide is:

2.45x10⁻³ moles × (323.2g / mol) =

<h3>0.792g of triphenyl bromide are produced.</h3>
