The experimental mass was 51.5 grams and the theoretical mass was 50 grams. what was the percent error? show your work below. round your answer to two digits.

3%

Experimental:

We are given that the experimental mass was 51.5 grams and the theoretical mass was 50 grams and we are to find the percent error.

We know the formula for the percent error:

Percentage error = (| experimental value - actual value | / actual value) * 100

So substituting the given values in the above formula:

Percent error = (51.5 - 50)/50 * 100 = 0.03 * 100 = 3%

the answer is na (sodium)
