The value of n for the given empirical formula and molecular mass is 5.00.

<u>Given the following data:</u>

  • Empirical formula = C_3H_5
  • Molecular mass = 205. 4 g/mol.

<u>Scientific data:</u>

  • Molar mass of carbon (C) = 12 g/mol.
  • Molar mass of hydrogen (H) = 1 g/mol.

To determine the value of n for the given empirical formula and molecular mass:

<h3>How to calculate molecular formula.</h3>

First of all, we would determine the gram-mass of the chemical compound as follows:

C_3H_5 = (12 \times 3)+(1 \times 5)

C_3H_5 = 36+5

C_3H_5 = 41 g/mol.

<u>For the </u><u>molecular formula</u><u>:</u>

(CH)n = 205.4

41n = 205.4

n =\frac{205.4}{41]

n = 5.00

10) A competency test has scores with a mean of 255 and a standard
melomori [17]

Answer:

The percentage of scores higher than 72 is 99.85%

Explanation:

The empirical rule states that about 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ)

We can use the relationship below

255-σ(61)=72

61σ=255-72

61σ=183

σ=3

The area is as shaded below

The percentage of scores higher than 72 is 99.7%+0.15%=99.85%
