Answer: A. It contains three times as many hydrogen atoms as carbon atoms.
Explanation: Empirical formula is the formula which shows the atoms of the elements in the simplest ratio of atoms whereas molecular formula show the actual number of atoms.
Thus if a compound has an empirical formula of , it means there are thrice number of hydrogen atoms as carbon atoms.
The molecular formula could be written as . Thus if number of carbon atoms are n, the number of hydrogen atoms are 2n.

The best way to make an accurate measurement of the height of a polar liquid is to take the reading from the lowest point of the meniscus.
<h3>What is the meniscus of a liquid?</h3>
The meniscus of a liquid is a curved that occurs at the top of a liquid placed in a container as a result of the attractive forces between the molecules of a the liquid.
Polar substances such as water have a concave meniscus as they dip downwards.
Therefore, the best way to make an accurate measurement of the height of a polar liquid is to take the reading from the lowest point of the meniscus.
