Number of moles and number of atoms in a 214 gram sample of silver?
According to the periodic table, silver (Ag) has an atomic mass of about 108 grams per mole. If you have 802 grams, set up a direct proportion where 108/1=802/x and solve for x. You get about 7.43 moles of silver.
How many moles are there in 5gram of sulphur?
Atomic mass of Sulphur is 32 1 mole = Atomic mass of sulphur No. of moles = Given mass/ Atomic mass No.of moles= 5/32 0.15 moles
How many moles of silver are there in 129 g of silver?
Since there are 107.8682 grams of Silver per mole, then 129 grams of Silver is 1.2 moles of Silver.
How many kilograms of silver are in 4.35 moles of silver?
4,35 moles of silver is equal to 469 g (0,469 kg).
Formula for moles?
number of moles = mass of the material/molar mass
How many moles of silver are contained in 7.00kg of silver?
About 64.8 moles assuming silver's atomic mass is 107.8682.
What is the mass of twenty two moles of silver fluoride?
22 moles AgF (126.9 grams/1 mole AgF) = 2791.8 grams of silver fluoride.
A smaple of silver with the same mass as the earth would contain how many atoms of silver and how many moles of silver?
its 125,524,727,836
How many moles of aluminum are present in 856g of aluminum sample?
Moles = Mass/ Relative Molecular Mass Aluminum forms Al2 compounds, so the relative molecular mass is 2 * 13 = 26. 856/26 = 32.9 (3sf)
What is the molar concentration of 7.25g of silver nitrate dissolved in 100 mL of solution?
No. moles = mass/molecular mass mass of silver nitrate = 169.88 7.25/169.88 = 0.042 moles/l but this is per 100ml so we need to multiply by 10 = 0.42m
How many moles in 108g of silver?
The atomic mass of the element silver, Ag is 108Amount of Ag = mass of sample/molar mass = 108/108 = 1.00 So, there is 1.00mol of silver in a 108g pure sample.
What is the difference between silver and gold?
gold is found in fewer amounts then silver moles of silver are heavier than moles of gold silver has a bright gray color gold has a bright yellow color
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 the mass in grams of 3.41x10e26 molecules of water?
first you divide by avagadro's number to get the number of moles. 3.41x10^26 / 6.022x10^23 = 566.25 moles The molecular mass of water is 18. moles is mass/molecular weight so moles by the mass is the weight. 566.25*18 is 10192.63g. This is 10.193kg. Are you sure your molecule count was not exponentially lower?
What is the mass in grams of 1.3 moles of silver?
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]
How many moles are in 2.5 moles of silver?
2,5 moles of silver is equal to 269,6705 g.
Is the moles of silver ions in water equal to silver nitrate solution moles?
no
