Number of Atoms in Methanol are calculated as,
Write chemical formula of Methanol,
CH₃-OH
Find out Subscripts:
There is only one subscript (₃) written after Hydrogen, it means there are 3 Hydrogen atoms attached to Carbon atoms.
Add all atoms in molecule:
Carbons = 1
Hydrogens = 4
Oxygens = 1
Total Atoms ______
6 Atoms
Answer:
The total mass of oxygen is 2.28x10^7 kg, silicon = 1.36x10^7 kg, ruthenium and rhodium = 5x10^-3kg each.
Explanation:
The first thing to do is to solve the total mass of Earth. That is done by multiplying the density with surface area and thickness. The total mass is 5x10^10 kg. The rates given for each compound are equivalent to 1 metric ton. That value is multiplied by the mass of Earth to determine each compound's total mass. The answers for oxygen, silicon and the two rarest non-radioactive elements are 2.28x10^7 kg, 1.36x10^7kg, 5x10^-3, respectively.
Boyle’s Law I’m pretty sure
