Molar mass is the mass of each element multiplied by subscript, then added together.
So, we’ll do
C = 12g x 12 = 144 g
H = 1g x 22 = 22 g
O = 16g x 11 = 176 g
The total of all of these is the molar mass: 342 g in a mol
The amount of mols of each element in each compound is likely equal to its subscripts.
C = 12 mols
H = 22 mols
O = 11 mols
For the atoms, you’ll multiply each one of the above by Avogadro’s number
Avogadro’s Number: 6.02 x 10^23 atoms/mol
The percent of the product would be 23

Answer:
The mass of the neon gas m = 1.214 kg
Explanation:
Pressure = 3 atm = 304 k pa
Volume = 0.57 L = 0.00057 
Temperature = 75 °c = 348 K
Universal gas constant = 0.0821 
We have to change the unit of this constant. it may be written as
Universal gas constant = 8.314 
Gas constant for neon = 
= 0.41 
From ideal gas equation,
P V = m R T ------- (1)
We have all the variables except m. so we have to solve this equation for mass (m).
⇒ 304 × 
× 0.00057 = m × 0.41 × 348
⇒ 173.28 = 142.68 × m
⇒ m = 1.214 kg
This is the mass of the neon gas.
The compound crystallizes in the aluminium trifluoride motif. Each fluoride is a doubly bridging ligand. The cobalt centers are octahedral.
CoF3 decomposes upon contact with water to give oxygen:
4 CoF3 + 2 H2O → 4 HF + 4 CoF2 + O2
It reacts with fluoride salts to give the anion [CoF6]3−, which is also features high-spin, octahedral cobalt(III) center.
