What is the density of a sample of vinegar if it was found that 35.6 cm3 of vinegar has a mass of 39.4g?

The answer is

Explanation:

The density of a substance can be found by using the formula

From the question

mass of ethanol = 39.4 g

volume = 35.6 cm³

It's density is

We have the final answer as

Hope this helps you

1.1g/cm³

Explanation:

The formula is [ d = m/v ] where m = mass and v = volume.

d = 39.4/35.6

d ≈ 1.1

Best of Luck!

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
