The number of hydrogen atoms is twice the number of oxygen atoms in ribose.
<h3>What is Ribose?</h3>
This is a sugar and a component of the ribonucleotides from which RNA is built. It has the formula C₅H₁₀O₅.
Ribose is a carbohydrate with the formula C₅H₁₀O₅. This molecule is a pentose monosaccharide which has a linear form 
. The hydroxyl groups lie on the same side in the form of Fischer Projections.
The number of hydrogen atoms is double the number of oxygen atoms. The ribose sugar is found in the RNA.
It is the genetic material which is found in some organisms that carry information from one generation to another.

The number of moles of O atoms in 8.18 g of Ba(NO₃)₂ is 0.364 mol.
<h3>What is moles?</h3>
"The mole is a SI unit of measurement that is used to calculate the quantity of any substance." It is denoted by mol.
Given that the mass of Ba(NO₃)₂ is 8.18 g
n = m/M
n = moles = ? mol Ba(NO₃)₂
m = mass(g) = 8.18 gram(NO3)2
The molar mass of Ba(NO₃)₂ is 261. 35g/mol.
As given, the moles of oxygen atom in Ba(NO₃)₂ is 6.
So, the moles of oxygen in 8.18 gram will be
Putting the value in the formula:
0.0607 mol Mg(NO3)2 × 6 mol O atoms/mol Mg(NO3)2 = 0.364 mol O atoms to three significant figures.
Thus, the number of moles of O atoms is 0.364 mol.
