Answer:
0.0001637 mol
Explanation:
PV = nRT
Very important formula in chem
2.3 atm * 0.0017 L = n * 0.082057 * 291 K
= 0.0001637 mol O2
This concept is very important in chem, practice it.
D. Hydrogen chemical bonds are found within water molecules.
Explanation:
TO calculate emperical formula , we need percentage composition of the elements and molecular mass of a specific compound which is already given in the question
then create a table with 1.name of element, 2.percentage given and its atomic mass , 3.no. of moles
( %given/at.mass of element) ... then take the least value in the no. of moles you have found now and divide with each no. of moles value .. to get a simple digit number.
You have got the empirical formula
