The nucleus of a comet is made up of rock, dust, and frozen gasses
hope this helps:)
Hey there!
Mass = 8.1 g
density = 1.65041 g/cm³
Volume = ?
Therefore:
D = m / V
<span>1.65041 = 8.1 / V
V = 8.1 / </span><span>1.65041 g
V = 4.907 cm</span>³
The sulfuric acid can be constituted into different concentrations using distilled water as a diluent.
<h3>What is dilution of acid?</h3>
Dilution of acid is defined as the decrease in the concentration of an acid using water.
For sulfuric acid to be diluted, it is slowly added to distilled water using the following guidelines:
- Add 150 ml of water to the beaker and add the desired amount of acid. This will give a diluted concentration of the given acid.

I’m confused what are you asking exactly?
Answer:
156 Hydrogen atoms
Explanation:
<u>Any acyclic alkane has a molecular formula that can be expressed as</u>:
CₙH₂ₙ₊₂
Where <em>n</em> is any integer and the number of carbon atoms. For example, Propane has 3 carbon atoms, this means it would have [2*3+2] 8 hydrogen atoms, resulting with a formula of C₃H₈.
An acyclic alkane with 77 carbon atoms would thus have:
2*77 + 2 = 156 hydrogen atoms
