How many dozens of copper atoms in a penny?
A US 1 cent piece prior to 1982 was made of copper and had a mass of about 3.1g. This is about 0.049 moles of copper, or around 2.9 x 1022 atoms. More recent pennies are mostly zinc (97.5%) and have a mass of about 2.5g. This works out to around 2.2 x 1022 zinc atoms and 5.9 x 1020 copper atoms, so overall around 2.3 x 1022 atoms.
Molar mass of copper?
To obtain one mole of copper atoms (6.02 x 1023 atoms), weigh out 63.55 g copper. The molar mass (M) of a substance is the mass of one mole of entities (atoms, molecules, or formula units) of the substance. Molar mass has units of grams per mole (g/mol).For More Detail63.546 grams of Copper in 1 mole of Copper(63.546g/mol) * (1mole/6.022*10^23) = 1.055*19^-22Another way (But for the Copper 35 iostope):1 atom of copper has 29 protons and 35 neutrons29 protons * 1.00728 amu/proton = 29.21112 amu35 neutrons * 1.00867 amu/neutron = 35.30345 amu29.21112 + 35.30345 = 64.51457 amu total(64.51457 amu) * (1 gram/6.02*10^23 amu) = 1.07167*10^-22 grams in one copper-35 atom

What is the molar mass of Mgl2?
278.11 grams. Also the sum of the masses of 1 mole of Mg and 2 mole of I
How many atoms are present in 31 grams of magnesium fluoride?
MgF2 has a molecular weight of 24+19*2 = 62g. Thus, 31 grams of MgF2 represent .5mol. There are 6.022*10^23 particles per mole. Since MgF2 has three atoms in it, we can find the number of atoms by the following: (.5 mol)(6.022*10^23 particles/mol)(3 atoms in MgF2) = ... Enjoy your free high school chemistry answer!

What is the mass of a sample of sodium that contains 2980 atoms?
Not much! 2980 atoms sodium [1 mole Na/6.022 X 1023 (atoms)][22.99 grams/1 mole Na] = 1.138 X 10 -19 grams sodium ====================
What is the in grams of one fluorine atom?
The mass in grams of one fluorine atom is 18.998 grams per mole. Fluorine is a gas that has the atomic number of 9.
What is the molar mass of calcium fluoride?
The formula is CaF2 so, its three atoms, one calcium and two fluorine atoms. add the molar mass of calcium(40 g/mol) and fluorine(19 g/mol X 2 because there are two atoms of fluorine) and you get 40+(19x2)=78 78 grams per mol

How many protons electrons and neutrons does 31potassium have?
From the periodic table, potassium has an atomic number of 19. This means that potassium atoms have 19 protons in their nuclei. In a neutral atom, the number of protons equals the number of electrons. Therefore, potassium atoms have 19 electrons. Mass number is the sum of protons and neutrons in the nucleus of an isotope. If you know the mass number and number of protons, subtract the number of protons from the mass number. In the case of potassium-31, the mass number is 31. So, subtract 19 from 31 and you get 12, which is the number of neutrons. So the atoms of potassium-31 has 19 protons, 19 neutrons, and 12 neutrons.
How many atoms are in a copper atom?
One atom. It contains 29 protons in its nucleus with 29 electrons orbitting. Hence copper (Cu) having the atomic number 29.
