Click "atomic mass" on the balance. This reading reports the mass of the particle in atomic mass units, or amu. Notice Carbon-12 weighs exactly 12.0000 amu. This is because Carbon-12 was used in defining the size of an amu. Officially, the atomic mass unit is defined at 1/12 the size of a Carbon-12 atom. This works out to mean a proton has mass equal to 1 amu. What is the mass of 1 neutron? Hint: Add a neutron to the atom. Watch how mass changes. O amu 1 amu 12 amu

Scientists in Huntsville just discovered a new element in Charger Village that they have called Pizzaium (Pz). There are two isotopes for this element. The first isotope has a mass of 546.7 amu and an abundance of 24.86%. The remainder of the element is accounted for by isotope 2 with a mass of 550. Given this information about the two isotopes, calculate the atomic mass for this element to four significant figures. If the last digit is a zero, Canvas will not take it, so leave it off.
An unknown element is determined to have two naturally occurring isotopes. Isotope 1 is 68.11% abundant and has a mass of 68.925580 amu, and isotope 2 has a mass of 70.9247005 amu. Determine the atomic mass of the unknown element. Express your answer to four significant figures.
Calculate the atomic weight of an atom with two stable isotopes. One isotope has an abundance of 69.15% and a mass of 62.930 amu. The second isotope has an abundance of 30.85% and a mass of 64.928 amu. Round your answer to two decimal places. Write your answer with the units in the blank below. Your work/solution for this problem needs to be included in the pages you need to submit for the midterm. Make sure you write the solution on a piece of paper with the appropriate set-up, units and round your answer according to SF.
