I believe the atomic level increases hope this helps.
Answer:
38 : 25
Explanation:
First thing's first, we have to confirm if the reaction is indeed balanced.
The equation of the reaction is given as;
C25H52 + 38 O2 → 25 CO2 + 26 H2O
From the reaction, 38 moles of O2 produces 25 moles of CO2
The ratio is given as;
38 : 25
Use M x V = M' x V'
0.300 x V = 0.100 x 250
V = .......... ml
Answer: The molecular formula will be 
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Empirical weight of
is
Molecular mass of compound is = 132 g
Now we have to calculate the molecular formula.
The molecular formula will be=
