If the experimental value for the percentage of O is 37%, The accepted value of the percentage of Oxygen is 40%, what is the error in the experiment? 6.5%08.1% 7.5% 5%

C) 7.5%

Explanation:

Accepted value of a substance can be said to be that number or "value" that is generally accepted by scientists worldwide.

Experimental value is that value is a substance that is gotten from experiments in the lab.

Experimental error then is the percentage difference between the accepted value and experimental value.

Percentage error = [(|experimental value - accepted value|) / (accepted value)] * 100%

Percentage error = [(|37 - 40|) / 40] * 100%

% error = 3/40 *100%

% error = 0.075 * 100

% error = 7.5%

the answer is true. hope it .
