What is the empirical formula for a substance that is composed of 40.66% carbon, 8.53% Hydrogen,23.72% Nitrogen, and 27.09% Oxyg

prohojiy [21]

Answer:

THE EMPIRICAL FORMULA OF THE SUBSTANCE IS C2H5NO

Explanation:

The steps involved in calculating the empirical formula of this substance in shown in the table below:

Element Carbon Hydrogen Nitrogen Oxygen

1. % Composition 40.66 8.53 23.72 27.09

2. Mole ratio =

%mass/ atomic mass 40.66/12 8.53/1 23.72/14 27.09/16

= 3.3883 8.53 1,6943 1.6931

3. Divide by smallest

value (0.6931) 3.3883/1.6931 8.53/1.6931 1.6943/1.6931 1.6931/1.6931

= 2.001 5.038 1.0007 1

4. Whole number ratio 2 5 1 1

The empirical formula = C2H5NO

<h3>Explanation:</h3>

Step 1: Define

11 g S

Step 2: Identify Conversions

[PT] Molar Mass of S - 32.07 g/mol

Step 3: Convert

Set up: $\displaystyle 11 \ g \ S(\frac{1 \ mol \ S}{32.07 \ g \ S})$
Multiply/Divide: $\displaystyle 0.343 \ mol \ S$

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

0.343 mol S ≈ 0.34 mol S
