Convert 614 Cal to J. Only include the numerical value in your answer. Respond with the correct number of significant figures in scientific notation.

Given parameters:

Number of given calories = 614 cal

Note that 1cal = 4.18J

Now to convert the given calories to joule, we use the relationship below:

Since 1Cal gives 4.18Joule of energy

614Cal will produce 4.18 x 614;

2566.52J of energy.

This written as 2.57 x 10³J because it has three significant numbers of 2, 5 and 7.

In writing an operation that involves deducing the significant numbers, we simply express our answer to that shows the lowest number of significant numbers. Our problem has 3 significant numbers each and the answer is given in that regard.
