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.
CHEMisTRY!

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.
How much oxygen is required to convert 14.0 grams of CO into CO2?
To convert 14.0 grams of CO into CO2, you need 16 grams of oxygen. This is because each molecule of CO reacts with one molecule of O2 to form one molecule of CO2. The molar mass of O2 is 32 g/mol, so 16 grams of oxygen is needed to convert 14.0 grams of CO.
How many moles is 14 g of CO gas?
To determine the number of moles in 14 g of CO gas, you need to first calculate the molar mass of carbon monoxide (CO), which is 28.01 g/mol. Then, divide the given mass by the molar mass to find the number of moles. In this case, 14 g of CO gas is equal to 0.499 moles.
Calculate the molar mass?
Example for sodium chloride, NaCl: - search in tables the atomic weights of the constitutive elements, Na and Cl: Na = 22,989 769 28 Cl = 35,453 - calculate the molar mass: MNaCl = ANa + ACl = 22,989 769 28 + 35,453 = 57,958 622 382

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.
If you have 345.23 grams of CO how many moles of CO do you have?
To do this, you need to know the molecular weight of the element you're dealing with, by adding up the atomic weights of the elements involved (found on any periodic table). The molecular weight is the mass in grams of the compound in one mole - this will provide you with a conversion factor. So take the measurement in grams and divide it by the molecular weight to convert to moles. Really what you're doing is multiplying the number by 1 mole, and dividing it by the equivalent of one mole, the molecular weight. That's the thought process behind unit analysis and how you get your "units to cancel".In this case, the answer is about 12.33 moles carbon monoxide.

5.34 grams W(CO)6 (1 mole W(CO)6/351.86 grams)(6 moles C/1 mole W(CO)6)(6.022 X 1023/1 mole C) = 5.48 X 1022 atoms of carbon ========================
If a bottle is filled with exactly 44.009 grams of carbon dioxide how many moles of molecules will it contain?
To calculate the number of moles of carbon dioxide (CO₂) in 44.009 grams, you can use the molar mass of CO₂, which is approximately 44.01 grams per mole. Using the formula: [ \text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} ] we find: [ \text{moles} = \frac{44.009 , \text{g}}{44.01 , \text{g/mol}} \approx 1 , \text{mole} ] Thus, the bottle contains approximately 1 mole of carbon dioxide molecules.
