What is the percentage of hydrogen in c2h4

jarptica [38.1K]

Ethylene- C2H4 = 85.7% Carbon and 14.3% Hydrogen

Find the atomic masses for each element and multiply it by the number of atoms in the compound, then add.

C- 12.0 * 2= 24.0

H- 1.00 * 4= 4.00

-----------------------

28.0

Take the masses for each element and divide it by the total mass. Then change the answer to get the percent.

C 24.0 / 28.0= .857 = 85.7%

H 4.00 / 28.0= .143 = 14.3%

<h3>Ethylene is 85.7% Carbon and 14.3% Hydrogen </h3>

A rectangular prism of volume 84 cm 3 has a mass of 760 g. What is the density of the rectangular prism? 5.8 g•cm 3 9.0 g/cm 3 6

Fiesta28 [93]

Answer:

9.0 g/cm³

Explanation:

Density can be computed with the formula:

$D=\dfrac{M}{V}$

Where:

D = Density

M = Mass

V = Volume

In your problem we are given:

84 cm³ = volume

760 g = mass

So we just plug in our given into the formula:

$D=\dfrac{M}{V}$

$D=\dfrac{760g}{84cm^{3}}$

$D=9.05g/cm^{3}$

The answer would then be:

9.0 g/cm³
