Atoms are composed almost entirely of empty space, about 99.99999999% empty space. Virtually all of the atom's mass is from its protons an neutrons. In cases where intense gravity has 'squeezed out' most of the empty space, such as in a neutron star, the matter is incredibly dense. This density is approximately equivalent to the mass of a Boeing 747 compressed to the size of a small grain of sand, or the human population condensed to the size of a sugar cube.

You have a sample of 75.6 g of C3H8. How many moles of C3H8 are in the sample?
dsp73

The number of moles that are contained in the given mass of propane (C_3H_8 is 1.7143 moles.

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

  • Mass of propane = 75.6 grams.

<u>Scientific data:</u>

  • The molar mass of propane = 44.1 g/mol.

To calculate the number of moles that are contained in the given mass of propane (C_3H_8):

<h3>How to calculate the moles of a compound.</h3>

In this exercise, you're required to determine the number of moles of propane that are contained in the given sample:

Mathematically, the number of moles contained in a chemical compound is given by this formula:

Number\;of\;moles = \frac{mass}{molar\;mass}

Substituting the given parameters into the formula, we have;

Number\;of\;moles = \frac{75.6}{44.1}

Number of moles = 1.7143 moles.

An ancient silver coin has a density of 10.49 g/cm3 at 20°C. If you break the coin that weighs 4.001 in half
Wittaler [7]

The density of each half of the coin is 10.49 g/cm3

In science density is defined as the ratio of mass to volume of an object.

Density is an intrinsic property.It is not affect by the amount of substance present.

This implies that each half of the broken coin must have the same density since it it is an inherent property of every silver material.

The density of each part of the coin therefore is  10.49 g/cm3.

Use chemical formulas to write the equation for the reaction between carbon and oxygen
Mandarinka [93]
C=Carbon
O=Oxygen
Oxygen is a diatomic molecule, so the subscript two needs to be used after the O in the formula.
C+O2->CO2
Hope this helps!
