It is \boxed{{\text{true}}} that it is never necessary to use more than one conversion factor.

Further Explanation:

The measurements are compared with each other with the use of standards called units. These units are divided into two categories which are basic and derived units.

The units that do not require any other unit for expressing themselves and are used to define other units are known as basic units. Mass, time, length and temperature are some basic units. But some units require basic units to describe them and these are known as derived units. Density, volume, and area are some of the derived units.

Following are 7 basic quantities along with their units in the SI system:

1. Length: Meter (m)

2. Mass: Kilogram (kg)

3. Time: Second (s)

4. Thermodynamic temperature: Kelvin (K)

5. Electric current: Ampere (A)

6. Amount of substance: Mole (mol)

7. Luminous intensity: Candela (Cd)

One unit can be converted into another one with the help of a proper conversion factor. Conversion factors are the ratios that are written in the form of fractions and multiplication of which with the original unit gives the desired units.

Consider the conversion of 500 g of any substance into kg. The conversion factor for this conversion is,

 1{\text{ g}} = {10^{ - 3}}{\text{ kg}}

Therefore the desired conversion is done as follows:

\begin{aligned}{\text{Mass of object}} &= \left( {500{\text{ g}}} \right)\left( {\frac{{{{10}^{ - 3}}{\text{ kg}}}}{{1{\text{ g}}}}} \right)\\&= 0.5{\text{ kg}}\\\end{aligned}

This is a single-step conversion. So it is never necessary to use more than one conversion factor.

In a solution of a carbonated beverage, what is the dissolved carbon dioxide?
insens350 [35]

Answer:

D.

Explanation:

D is the correct answer because, in aqueous solution, solvent is water and solute (in this example carbon dioxide CO₂) is a substance dissolved in water. The amount of solute that can be dissolved in a solvent depends of chemical composition, temperature and pressure

Assuming 100% dissociation, calculate the freezing point and boiling point (in °C) of a solution with 83.6 g of AgNO 3 in 1.00 k
Thepotemich [5.8K]

Answer:

  • <u>Freezing point: - 1.83ºC</u>
  • <u>Boiling point: 100.50ºC</u>

Explanation:

The <em>freezing point</em> and<em> boiling point</em> of solvents, when a solute is added, will change accordingly to the concentration of the solute particles.

The freezing point will decrease and the boiling point will increase. These are two colligative properties.
