What mass of gold contains the same number of atoms as 9.00g of Aluminum?
66
What mass of arsenic in grams contains the same number of atoms as 39.95 g of Argon?
74.92 grams of arsenic, approx.
What is isotopy?
is a phenomenom whereby atoms of the same compound have the same atomic number but different mass number
When two atoms appear to have the same mass number they?
must have the same number of protons + neutrons.
The mass of oxygen which contains the same number of atoms as those present in 64 grams of sulfur is?
The gram-atomic mass of sulphur is 32 and that of oxygen is 16, to two significant digits. Therefore, the mass of oxygen with the same number of atoms as 64 grams of sulphur can be found from the proportion m/64 = 16/32, or m = 32 grams.
What mass of gold contains the same number of atoms as 9.00g of Aluminum?
66
Which sample contains the same number of atoms as a gram atomic mass of he?
A gram atomic mass of helium (He) contains the same number of atoms as 1 mole of helium. Since 1 mole of any substance contains approximately 6.022 x 10^23 atoms, a sample of helium with a gram atomic mass would contain that same number of atoms.
What mass of sodium metals contains the same number of atoms as 12.00g of carbon?

What mass of iodine contains the same number of atoms as 25.0 grams of chlorine?
861.9g i believe
What mass of hydrogen contains the same number of atoms as 8.65 g of nitrogen?
0,617 g
What mass of arsenic in grams contains the same number of atoms as 39.95 g of Argon?
74.92 grams of arsenic, approx.
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

What is an element that has the same atomic number but different mass numbers?
If a sample of an element contains atoms of different mass numbers, the name of the element followed by a hyphen and the mass number is the name of an isotope of the element.
What's the difference between an atomic number in the mass number of an Atom?
All the atoms of a particular element have the same atomic number (number of protons). The atoms of different elements have different numbers of protons. For example, all oxygen atoms have 8 protons and all sodium atoms have 11 protons. The mass number of an atom is the total number of protons and neutrons it contains.
What is the mass of potassium if a potassium sample contains 5 times the number of atoms as in 9.85 grams of gold?
The gram atomic mass of gold is 196.967 and that of potassium is 39.0983. Therefore, equal numbers of atoms of potassium are supplied by 39.0983/196.967 the mass of potassium compared with gold. 5 X 9.85 = 49.25. This contains the same number of gold atoms as 49.25(39.0983/196.967) or 9.78 grams of potassium contains of potassium atoms, to the justified number of significant digits (limited by the number "9.85", assuming that "5" is intended to be exact.)
What are atoms that have the same number of protons but different mass number?
isotopes
What are atoms with the same atomic number but different mass called?
Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
