These values were recorded as the mass of products when a chemical reaction was carried out three separate times: 8.83g; 8.84g; 8.82g. The mass products from that reaction is 8.60g. The values are:. a. accurate, but not precise
b. precise, but not accurate
c. both accurate and precise
d. neither accurate nor precise

The answer to your q it is false

Yeah give more information 

Most elements have more than one naturally occurring isotope. as you learned previously, the atoms of those isotopes have the same atomic number (number of protons), making them belong to the same element, but they have different mass numbers (total number of protons and neutrons) giving them different atomic masses. so which mass is put on the periodic table for each element? is it the most common isotope’s mass? the heaviest mass? this activity will answer that question.
