Answer:
The difference between accuracy and precision is both precision and accuracy are two ways of how scientists think about error. However, accuracy refers to or meaning to how close a measurement is to the true or accepted value. On the other hand, precision refers to or meaning to how close measurements of the same item are to each othe .... But scientists use the best quality of scientific observations and are both accurate and precise.
The molar mass of CO2 is 44 grams per mole.
165 grams / 44 grams per mole of CO2 = 3.75 moles CO2
Using Avogadro’s law where 1 mole of substance equals
6.023 x 10^23 molecules
3.75 moles CO2 (6.023 x 10^23 molecules /mole) = 2.26 x 10^24 molecules CO2
