54 is 70.13% of 77.
What is -54 minus 23?
(-54) - 23 = -77
What number comes between 77 and 90?
78 - 89 are the numbers that come between 77 and 90.
How far apart is 27 and -54 on a number line?
To find the distance between 27 and -54 on a number line, you can subtract the smaller number from the larger number. The calculation is |27 - (-54)| = |27 + 54| = |81|. Therefore, the distance between 27 and -54 is 81 units.
What number is halfway between 54 and 64?
the mean of 54 and 64 : (54+64)/2 = 59

Can 54 go into 77?
54 doesn't go evenly into 77. 54 goes into 77 once with a remainder of 23.
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.
An atom of an element has 54 protons some of the elements atoms have 77 neutrons while other atoms have 79 neutrons what are the atomic numbers and mass numbers of the two types of atoms of this el?
The atomic number for an element with 54 protons is 54. For the atoms with 77 neutrons, the mass number would be 54 (protons) + 77 (neutrons) = 131. For the atoms with 79 neutrons, the mass number would be 54 (protons) + 79 (neutrons) = 133.

What number comes between 77 and 90?
78 - 89 are the numbers that come between 77 and 90.
How far apart is 27 and -54 on a number line?
To find the distance between 27 and -54 on a number line, you can subtract the smaller number from the larger number. The calculation is |27 - (-54)| = |27 + 54| = |81|. Therefore, the distance between 27 and -54 is 81 units.
How many protons neutrons and electrons are in xenon?
The protons and neutrons are packed together in the middle and the electrons have space to move, around them. logically their should be MORE neutrons and protons,but this depends on the size of the atom and how many atoms in the neon. info from SUSSEX UNIVERSITY.
