Answer:

The number of elements in a compound is counted by identifying and counting the chemical symbols represented in the chemical formula

A compound is a substance that is a mixture of more than one elements.

Compounds are made of two or more elements. These elements are represented by their symbols. These symbols can be identified and the number of elements represented by these symbols are counted.

For example, in the compound H_2OH

O :

H represents Hydrogen

O represents Oxygen

The elements in Water ( H_2OH

O ) are Hydrogen and Oxygen

Therefore, the number of elements in H_2OH

O is 2

Also in, NaClNaCl

The elements are Sodium(Na) and Chlorine(Cl)

There are two elements in NaCl

Hence, the number of elements in a compound is counted by identifying and counting the chemical symbols represented in the chemical formula

If 60 grams of a liquid takes up 120ml how dense is the liquid

Black_prince [1.1K]

Answer:

<h2>Density = 0.5 g/mL</h2>

Explanation:

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

<h3> $Density = \frac{mass}{volume}$ </h3>

From the question

mass = 60 g

volume = 120 mL

Substitute the values into the above formula and solve

That's

<h3> $Density = \frac{60}{120} \\ = \frac{1}{2}$ </h3>

We have the final answer as

<h3>Density = 0.5 g/mL</h3>
