A substance where almost all have the same atomic number of protons
1 kpa = 0.0098692327 atm so just multiply that by 45.6
Answer:
picograms
Explanation:
Please see attached picture for full solution.
M(C2H2O)= 12.0*2 +1.0*2 +16.0 = 42 g/mol is a molar mass for empirical formula.
120.6g/mol/42g/mol ≈ 3
So, empirical formula should be increased 3 times,
and molecular formula is C6H6O3.
Answer is D.
