The average mass of 3 men is 77kg The average mass of 2 of the men is 72.5kg What is the mass of the 3rd man?
The everage mass of three men is: (a + b) / 3 = 77, where a is mass of two first men combined and b is a mass of third man. The everage mass of two men is: a / 2 = 72.5, therefore a = 145, and (145 + b) / 3 = 77 145 + b = 231 b = 231 - 145 = 86 Answer: Mass of the third man is 86 kg.
What element has the atomic number 77?
Well, I couldn't get any stable element with mass number of 77. However the closest ones are arsenic with mass number 75 or selenium with mass number 79. Note: All the following elements listed below have isotopes with mass number 77, but are unstable with half life ranging from a few hours to nano seconds: Nickel, Copper, Zinc, Galium, Germanium, Arsenic, Selenium, Bromine, Krypton, Rubidium, Strontium and Yttrium. If you had meant atomic number, then iridium has the atomic number of 77.
Which element has 77 protons in its nucleus?
Xenon. Take the atomic mass of 131 and subtract it's protons 54, to get 77 neutrons.

An isotope of xenon has an atomic number of 54 and contains 77 neutrons. What is the mass number of the xenon isotope?
The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.
