A silver sample contains 52 atoms each having 60 neutrons and 48 atoms each having 62 neutrons What is the sample's average atomic mass?
The total mass of all the silver atoms would be 10,770,65(47+60) + 35(47+62) = 10,770 The total number of silver atoms is 100, 65 + 35 = 100 Dividing the total mass by the number of atoms gives us a 10770/100 = 107.7 for an atomic mass by these numbers.
What is the mass of 5.44 x 10 to the 25 power atoms of silver?
By definition, Avogadro's Number, about 6.022 X 1023, for an element is the number of atoms in one gram atomic mass. The gram atomic mass of silver is 107.868. Therefore, the mass of 5.44 X 1025 atoms of silver is [(5.44 X 1025)/(6.022 X 1023)] X 107.868 or 974 grams, to the justified number of significant digits.
What is the mass of 3.30 x 10 to the 23 power of atoms of silver?
107.8682
How many atoms are present in a piece of sterlingsilver jewelry weighing 33.14?
How many atoms are present in a piece of sterlingsilver jewelry weighing 33.14 ? (Sterling silver is a silver-copper alloy containing 92.5% by mass.)
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.

How much mass would two atoms of silver have?
Atomic weight of silver: 107,868 2 u Avogadro's number: 6,022 141 79.1023 1 atom-gram of silver = 6,022 141 79.1023 silver atoms weight of 1 silver atom = 107,8682/6,022 141 79.1023 = 17,9119.1023 grams

How many protons neutrons and electrons does 96 silver have?
The term silver-96 indicates a mass number of 96 for that isotope of silver. The mass number of an isotope is the sum of protons and neutrons in the nuclei of its atoms. On the periodic table, the atomic number for silver is 47. The atomic number of an element is the number of protons in the nuclei of its atoms. The difference between the mass number and atomic number is the number of neutrons in the nuclei of the atoms of that isotope. In a neutral atom, the number of protons and electrons are equal. Therefore, silver-96 has 47 protons and 47 electrons in its atoms. The number of neutrons = 96 - 47 = 49.
What is the mass of 35 Xenon atoms in grams?
Approx 7.63*10^-21 grams or 7.63 zeptograms.
What mass of gold contains twice as many atoms as 2.74g of silver?
The gram atomic mass of silver is 107.868 and that of gold is 196.967. Equal numbers of gram atoms of different elements contain equal numbers of atoms. Therefore, the mass of gold required to contain twice as many atoms as 2.74 g of gold is (2 X 2.74 X 196.967)/107.868 or 10.0 g of gold, to the justified number of significant digits.
How many atoms are present in a piece of sterlingsilver jewelry weighing 33.14?
How many atoms are present in a piece of sterlingsilver jewelry weighing 33.14 ? (Sterling silver is a silver-copper alloy containing 92.5% by mass.)
What is the number of atoms in 20.5 g silver?
Silver (Ag) has a molar mass of 107.87g/mol, so by dividing 20.5 by its molar mass, you get how many moles of silver atoms there are in that much silver.(20.5gAg)(1mol/107.87g) = 0.190 moles silver atomsNow, 1 mole = 6.02*1023 (Like a dozen = 12, a mole is just a value.) so if you can't answer in moles, just multiply 0.190 moles by 6.02*10230.190 mol*(6.02*1023/1mol)= 1.14*1023 silver atoms
What is sliver made out of?
Silver is an element, it is made of silver atoms and only silver atoms.
How many ag atoms are there in 0.0001 grams of Ag.Molar mass of Ag is 108 gram per mole?
Using your molar mass. 0.0001 grams silver (1 mole Ag/108 grams)(6.022 X 1023/1 mole Ag) = 5.58 X 1017 atoms of silver =====================
