Enter the mass and calorific value into the calculator to determine the energy content. This calculator can also evaluate any of the variables given the others are known.
Grams To Joules Formula
The following formula is used to calculate the energy content in joules of a substance given its mass in grams.
E = m * CV
Variables:
- E is the energy content (Joules)
- m is the mass of the substance (grams)
- CV is the calorific value or heat of combustion of the substance (Joules/gram)
To calculate the energy content in joules, multiply the mass of the substance in grams by its calorific value or heat of combustion. The result will be the energy content of the substance in joules.
What is Grams To Joules?
Grams to Joules is a conversion process used in physics and chemistry to convert the mass of a substance (measured in grams) to the amount of energy it contains (measured in joules). This conversion is typically used in the context of energy content of fuels or food, and it requires knowledge of the specific energy content of the substance in question, often referred to as its heat of combustion or calorific value.
How to Calculate Grams To Joules?
The following steps outline how to calculate the energy content in Joules using the formula E = m * CV.
- First, determine the mass of the substance (m) in grams.
- Next, determine the calorific value or heat of combustion of the substance (CV) in Joules/gram.
- Next, gather the formula from above: E = m * CV.
- Finally, calculate the energy content (E) in Joules.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
mass of the substance (m) = 50 grams
calorific value or heat of combustion of the substance (CV) = 10 Joules/gram
