Final answer:
The mass number of an element with 27 protons and 32 neutrons is 59.The mass number of this element is 27 + 32 = 59.
Step-by-step explanation:
The mass number of an element is the sum of its protons and neutrons. For an element that has 27 protons, 27 electrons, and 32 neutrons, the mass number can be calculated by adding the number of protons to the number of neutrons. Therefore, the mass number of this element is 27 protons + 32 neutrons = 59.The mass number of an element is the sum of the protons and neutrons in its nucleus. In this case, the element has 27 protons, 27 electrons, and 32 neutrons. So, the mass number is calculated by adding the number of protons and neutrons: mass number = number of protons + number of neutrons. Therefore, the mass number of this element is 27 + 32 = 59.
