How many CCl4 molecules of different masses can exist?

Why one mole of different compounds have different masses but have same number of molecules?
One mole of different compounds have different masses but have same number of molecules because that is the definition of a mole - a mole is about 6.022x1023 molecules of any particular material - and is normalized to the mass of Carbon-12.
Why one mole of hydrogen molecule and one mole of hydrogen atoms have different masses?
because there are 2 hydrogen atoms in the molecule of hydrogen atoms
What is heavier Hydrogen gas or oxygen gas How do you know?
Oxygen is heavier as it has a mass number of 16 whereas hydrogen has a mass number of 1. Both form diatomic molecules (molecules of two atoms) making the formula masses 32 for oxygen and 2 for hydrogen.
Why one mole of hydrogen molecule and 1 mole of hydrogen atoms have different masses?
1 mol of hydrogen molecule = 1 mol of H2 = molar mass of H2 = 2.0gmol-1 2.0gmol-1 x 1mol = 2.0g 1 mol of hydrogen atom = 1 mol of H = molar mass of H = 1.0gmol-1 1.0gmol-1 x 1mol = 1.0g Hence, they have different masses
Why one mole of hydrogen molecules and one mole of hydrogen atoms have different masses?
Because each hydrogen molecule contains 2 hydrogen atoms!
What are the relative formula masses of hydrogen molecules?
The relative formula is like a career of someones jobs they do
The different molecules that make up the air in a room have on average the same kinetic energy how does the speed of the different air molecules depend on their masses?
If mixed together, molecules with various masses will move at different speeds related to their mass.

How does the speed of different molecules depend on their masses?
they depend on their masses because they would drop if you dont have mass ya mums cool dude
How many types of molecules with different masses exist in a sample of chlorine gas if the same exists entirely as diatomic molecules?

Why do different liquids have different viscossities?
Different liquids are made up of different types of molecules, which have different masses, different forces between them, etc.
Is Density is the measurement of the number of atoms or molecules in a given volume?
Density is the relationship between mass and volume. the number of molecules in a given mass is molarity. -------------------------------------------------- No it is not. Because atoms come with different masses, so you could have 1 billion atoms of hydrogen occupying the same volume as 1 billion atoms of gold but the gold would weigh more than the hydrogen.
