If 75 percent of the isotopes of an element have a mass of 35.0 amu and 25 percent of the isotopes have a mass of 37.0amu what is the atomic mass of the element?
The atomic mass is calculated by averaging the masses of the isotopes based on their abundance. In this case, 75% of the isotopes have a mass of 35.0 amu and 25% have a mass of 37.0 amu. Atomic mass = (0.75 * 35.0 amu) + (0.25 * 37.0 amu) = 35.5 amu.
How do you find the number of proton and atomic number in the mass number 75?
You have to know the element with the mass number of 75. Then you would look it up on the periodic table to find the atomic number, which is the number of protons.
What is mass number of arsenic?
The mass number of arsenic is 75, as it is the sum of the number of protons and neutrons in the nucleus of an arsenic atom.
