A literature value is **a constant or known, extensively verified value that can be used in experimental or theoretical calculations**.

What is a ” literature value ” in the laboratory?

**In**the laboratory, researchers work with theoretical and experimental**literature**values. The theoretical**literature value is**the**value**that**is**expected based on the reactions taking place.

## How do you find literature values in chemistry?

**Literature values** may be found in references or in journals. In the laboratory, researchers work with theoretical and experimental **literature values**.

## What is experimental value in chemistry?

The **experimental value** is the **value** that you get in an experiment. The absolute **value** of the difference between the two **values** (the “error”) is your **experimental** error. For example, suppose that you did an experiment to determine the boiling point of water and got a **value** of 99.3 °C. Your **experimental value** is 99.3 °C.

## What is chemical literature?

**Chemistry**: **Chemical Literature**. Includes sources for background information, **chemical literature**, **chemical** properties (including spectra), as well as safety information and sources for material safety data sheets (MSDS).

## What is the difference between accepted value and experimental value?

**accepted value**: The true or correct **value** based on general agreement **with a** reliable reference. error: The **difference between** the **experimental** and **accepted values**. **experimental value**: The **value** that is measured during the **experiment**.

## What is a literature value meaning?

View this answer. A **literature value** is a constant or known, extensively verified **value** that can be used in experimental or theoretical calculations.

## What is a good percent error?

Explanation: In some cases, the measurement may be so difficult that a 10 % **error** or even higher may be acceptable. In other cases, a 1 % **error** may be too high. Most high school and introductory university instructors will accept a 5 % **error**. But this is only a guideline.

## What is true value in chemistry?

In theory, a **true value** is that **value** that would be obtained by a perfect measurement. Since there is no perfect measurement in analytical **chemistry**, we can never know the **true value**. Errors in analytical **chemistry** are classified as systematic (determinate) and random (indeterminate).

## How do you calculate precision?

**How to Calculate Precision**

**Determine**the Highest and Lowest Values.- Subtract the Lowest Value From the Highest.
- Report the Result.

## How is accepted value determined?

**Accepted value** is sometimes called the “true” **value** or “theoretical” **value**, so you might see the formula written in slightly different ways: PE = (|true **value** – experimental **value**| true **value**) x 100%. PE = (|theoretical **value** – experimental **value**| theoretical **value**) x 100%.

## Is a high percent error good or bad?

Explanation: In some cases, the measurement may be so difficult that a 10 % **error** or even **higher** may be acceptable. In most cases, a **percent error** of less than 10% will be acceptable. Similarly, **is a high percent error good or bad**? Since MAPE is a measure of **error**, **high** numbers are **bad** and low numbers are **good**.

## What does percent error tell you about accuracy?

**Percent error is the accuracy** of a guess compared to the actual measurement. It’s found by taking the absolute value of their difference and dividing that by actual value. A low **percent error** means the guess is close to the actual value.

## When Should percent difference be used?

**Percentage Difference** is **used** when both values mean the same kind of thing (for example the heights of two people).
