Mass is a fundamental quantity

<h3>What is fundamental quantities?</h3>

Fundamental quantities can be defined as those physical quantities which forms the basic unit of measurement. They are the quantities upon which other quantities and units are derived from.

Mass is measured in kilograms (kg)

Other examples of fundamental quantities apart from mass are as follows:

  • Length
  • Time
  • Amount of substances
  • Luminous intensity
  • Temperature
  • Magnetic flux

So therefore, the tool or instrument which is used to measure an object’s mass is electronic balance

¿Cuál es el % m/m de una disolución en que hay disueltos 22 g de soluto en 44 g de disolvente?
Archy [21]

The question is as follows: What is the% m / m of a solution in which 22 g of solute are dissolved in 44 g of solvent?

Answer: The% m/m of a solution in which 22 g of solute are dissolved in 44 g of solvent is 50%.

Explanation:

Given: Mass of solute = 22 g

Mass of solvent = 44 g

The percentage m/m is calculated using the following formula.

Mass percentage = \frac{mass of solute}{mass of solvent} \times 100

Substitute the values into above formula as follows.

Mass percentage = \frac{mass of solute}{mass of solvent} \times 100\\= \frac{22 g}{44 g} \times 100\\= 50 percent

Thus, we can conclude that the% m/m of a solution in which 22 g of solute are dissolved in 44 g of solvent is 50%.
