What is the atomic mass for cobalt?
57 grams Florine (1 mole F/19.00 grams)(6.022 X 10^23/1 mole F) = 1.8066 X 10^24 atoms Florine 1.8066 X 10^24 atoms (1 mole Co/6.022 X 10^23)(58.93 grams/1 mole Co) = 176.79 grams of cobalt ( sigi figi might be 180 grams )
How many moles of atoms are contained in 22.6 g of the Co?
1 mole Co = 58.933g Co (atomic weight in grams)1 mole Co atoms = 6.022 x 1023 atoms CoConvert grams Co to moles Co.22.6g Co x (1 mole Co/58.933g) Co = 0.383 mole CoConvert mole Co to atoms Co.0.383 mole Co x (6.022 x 1023 atoms Co/1 mole Co) = 2.31 x 1023 atoms Co
What is the mass in grams of 0.0489 mol cobalt?
To find the mass of cobalt in grams, you need to multiply the number of moles by the molar mass of cobalt. The molar mass of cobalt is approximately 58.93 g/mol. Therefore, the mass of 0.0489 mol of cobalt is 0.0489 mol x 58.93 g/mol ≈ 2.88 grams.
Why do 1 mole of cobalt weigh more than 1 mole of boron?
what you are asking is why cobalt is more dense than boron. You will have to ask a higher power than I. But I will do what I can. atoms are weighed in AMU atomic mass units. Atoms are measured in angstroms. so an atomic density is the relation of angstroms the atom fills(volume)to how heavy it is(mass). Oh, and the mole is a very large number of atoms or molecules so that these really small weights and sizes become tangeable a.k.a. cubic inches, ounces, pound, cubic yards. Now why is there a difference in density of these substances... well they have more or less protons, neutrons, and electrons. Not to mention different arrangement of the electrons causes a different size. I hope that helped.
What is the mass of 1 mole of carbon monoxide?
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ration of isotopes equal to that in nature - has a mass of 12.0107 grams.
What is molar mass of cobalt?
Molar mass of cobalt III sulfate is 406.04 (g.mol-1)How it's done:Establish the molecular formula: Co2(SO4)3Then:Add up all atom mass's2 * 58.93 = 117.86 (for 2 Cobalt)3 * ( 32.06 + 4*16.00 )= 288.18 (for 3 Sulfate)Finally:Totalize: 406.04
What is the dissociation of cobalt II nitrate?
Cobalt(II) nitrate dissociates as follows:Co(NO3)2 ==> Co^2+ + 2NO3^-
Which has a lower atomic mass lead or cobalt?
Cobalt has a lower atomic mass than lead. The atomic mass of cobalt is approximately 58.93 g/mol, whereas the atomic mass of lead is about 207.2 g/mol.
What is the mass of one mole of CO in grams?
Cobalt (III) hydroxide's formula is Co(OH)3 MOLES are found by grams you have/ molar mass of the molecule. To find the molar mass, you must first find the masses of the elements. In Co(OH)3 there are 3 elements: Cobalt (Co), Oxygen (O), and Hydrogen (H) Cobalt's atomic mass is 58.933 (but we'll round that 59) Oxygen's atomic mass is 15.999 (but we'll round that 16) Hydrogen's atomic mass is 1.0079 (but we'll just call that 1.) BUT WAIT. THERE'S MORE. There is 1 Cobalt atom, so we'll keep 59. There are THREE Oxygen atoms, so we have to multiply 16 by 3. (That's 48.) And there are also THREE Hydrogen atoms, so we have to multiply 1 by 3. (That's 3, but I'm sure you knew that.) So let's add them up: 59 + 48 + 3 = 110 grams. Almost there! 3.96 /110 = .036 moles.
