Mass: kilogram (kg)
Length: metre (m)
Volume: cubic metre (m^3)
Temperature: kelvin (K)
The general properties of matter result from its relationship with mass and space. ... Because it occupies space, all matter has volume and impenetrability, since two objects cannot occupy the same space simultaneously.

Explanation:
Hello,
In this case, we are asked to compute the by mass percent for the given 3.2 g of ethylene glycol in 43.5 g of water. In such a way, since the by mass percent is computed as follows:
Whereas the solute is the ethylene glycol and the solvent the water, therefore we obtain:
Best regards.
Answer:
C₄H₆
Explanation:
A hydrocarbon is a molecule that only contains atoms of Carbon and Hydrogen. As you remember, the molar mass of Carbon is 12g/mol and the molar mass of Hydrogen is 1g/mol.
To solve this question we can find the amount of Carbons necessary that doesn't exceed the 54g/mol. That is:
54g/mol / 12g/mol = 4.5
As the molecular formula must be given in whole numbers, the amount of Carbons is 4. This 4 carbons have a mass of:
12g/mol*4 = 48g/mol
And the hydrogens necessaries to suply the molecular mass are:
54 - 48 = 6 hydrogens
That means molecular formula is:
<h3>C₄H₆</h3>
