There are 107.9 grams in one mole of pure silver. 107.9 a.m.u. is the average mass of isotopes of the element silver
Answer to another (= not this one) question:
The atomic number is the number of grams in a mole of any element. Hydrogen has an atomic number of 1 so a mole of hydrogen (okay, a half-mole of H2) weighs 1 gram.
[ Silver is not Hydrogen ! and an atom is not a molecule]
For this you need the Atomic Mass of Ag. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.
1.3 moles Ag × (107.9 grams) = 140.3 grams Ag
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Carbon's atomic mass is 12.011 grams.
To find the number of moles in 13 grams of NaCl, you need to divide the given mass by the molar mass of NaCl. The molar mass of NaCl is 58.44 g/mol. Therefore, 13 g of NaCl is equal to 0.222 moles.
Formal set up. ( Avogadro's number appears as form of 1 here ) 9.00 grams 13C (1 mole 13C/13.00 grams)(6.022 X 1023/1 mole 13C)(1 mole atoms 13C/6.022 X 1023) = 0.692 mole of 13C atoms ====================
To find the number of electrons in 9.00 grams of carbon-13, we first need to determine the number of moles of carbon-13 in 9.00 grams using its molar mass. Then, we multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of atoms. Since carbon-13 has 6 electrons, the total number of electrons would be 6 times the number of atoms.
To calculate the number of moles, you first need to find the molar mass of titanium, which is 47.867 g/mol. Then, you can use the formula moles = mass/molar mass to find the answer. In this case, moles = 71.4g / 47.867 g/mol ≈ 1.49 moles of titanium.

0,666 moles
To find the mass of 5.20 x 10^22 molecules of F2, first calculate the molar mass of F2 (38.00 g/mol). Then, convert the number of molecules to moles by dividing by Avogadro's number (6.022 x 10^23). Finally, multiply the moles by the molar mass to get the mass in grams, which is approximately 3.1 grams.
To find the number of moles of carbon atoms in 1.574 g of Novocain (C13H21N2O2Cl), first calculate the molar mass of the compound. The molar mass is 13(12.01 g/mol) = 156.13 g/mol for the carbon atoms. Next, divide the given mass of Novocain by its molar mass to get the number of moles of Novocain. Finally, since each molecule of Novocain contains 13 carbon atoms, multiply the number of moles of Novocain by 13 to get the number of moles of carbon atoms.
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O= 18.0 grams500.0 grams H2O / (18.0 grams) = 27.8 moles H2O
To find the number of electrons in 9.00 grams of carbon-13, we first need to determine the number of moles of carbon-13 in 9.00 grams using its molar mass. Then, we multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of atoms. Since carbon-13 has 6 electrons, the total number of electrons would be 6 times the number of atoms.
For every 1 mole of butane (C4H10) burned, 13 moles of oxygen (O2) are required. Therefore, to burn 4.8 mol of butane, you would need 4.8 x 13 = 62.4 mol of oxygen. To convert this to grams, you would multiply the number of moles of oxygen by its molar mass (32 g/mol). So, 62.4 mol x 32 g/mol = 1996.8 grams of oxygen.
The density of the substance is calculated by dividing the mass (169 grams) by the volume (13 milliliters). Therefore, the density of the substance is 169 grams / 13 milliliters = 13 grams per milliliter.
you tell me
The mass of one carbon-13 atom is approximately 13 atomic mass units (u). Therefore, the mass of one mole of carbon-13 atoms is 13 grams.
