What is the mass number of the atom Kr?
Krypton, Kr mass number: 83.8 atomic number: 36
How do you convert 1.29 mol Kr to a number of atoms?
Just multiply the moles of Kr by Avogadro's number. Formal set up.1.29 moles Kr (6.022 X 1023/1 mole Kr)= 7.77 X 1023 atoms of krypton====================
What is the atomic mass and atomic number of Kr in the periodic table?
Atomic number: 36 Atomic mass: 83.8
How many protons does Kr-83 have?
An element's atomic number gives its number of protons. Krypton's atomic number is 36. Thus it has 36 protons, regardless of the isotope.
Which of the atoms in the table are isotopes of krypton Kr?

What mass of He contains the same number of atoms as 5.0 g Kr?
To find the mass of He containing the same number of atoms as 5.0 g Kr, we need to use the fact that atoms are indivisible entities. First, determine the number of atoms in 5.0 g Kr using the molar mass of Kr. Then, calculate the mass of He containing the same number of atoms by dividing the atomic mass of He by Avogadro's number and scaling it up to match the number of Kr atoms.
How many Kr atoms are there in 2.51 moles of Kr?
The number of atoms is 15,11.10EX23.
What fourth period representative element has the highest atomic number Ca Kr Pb Zn?
Kr fourth period means the fourth horizontal row on the periodic table....so the element on that row with the highest atomic number is Kr
What mass in g does 7.98 moles of Kr have?
7.98 moles of Kr have 668,708 g.
How many moles of Kr are contained in 398 mg of Kr?
The mass of 1 mole of an element is its atomic weight on the periodic table in grams.1g = 1000mgThe mass of 1 mole of Kr = 83.80g KrConvert mg Kr to g Kr.398mg Kr x (1g/1000mg) = 0.398g KrConvert g Kr to mol Kr.0.398g Kr x (1mol Kr/83.80g Kr) = 4.75x10-3mol Kr
