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.

m=n * Mr which is mass=number of moles multiplied by molar mass.
So,
m=1*(12.01+16.00)
= 28.01g

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?
To calculate the molar mass of a compound, you need to sum the atomic masses of all the elements present in the compound. The atomic masses can be found on the periodic table. Add up the atomic masses of each element in the compound to get the molar mass in grams per mole.

What is the molar mass for carbon moxoxide CO?
Molecular mass of CO = atomic weight of O + atomic weight of C = 28,01 g
How many moles of CO in 1.23g of it?
For this you need the atomic (molecular) mass of CO. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.4.5 grams / 28.0 grams = .161 moles CO
What is the mass of one mole in urea?
Pure Urea (H2N-CO-NH2) has a mole wt of 60.06. SO ... 60.06 gm is one gm mole.
If you have 345.23 grams of CO how many moles of CO do you have?
To convert grams to moles, you need to use the molar mass of CO (carbon monoxide), which is 28.01 g/mol. Divide the given mass (345.23 g) by the molar mass to get the number of moles. So, 345.23 g / 28.01 g/mol = 12.31 mol of 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.
