Ответ:
First you need to find the molar mass of pentane.
Molar mass of C is 12.01 and molar mass of H is 1.008.
12.01*5 +1.007*12 = 60.05 + 12.08 = 72.13 grams C5H12 per mole
54.11/72.13 = 0.75 moles C5H12
So your answer is 0.75 moles C5H12
Ответ:
The balanced chemical equation will be;
NaHCO3 + CH3COOH = CH3COONa + H2O + CO2
After balancing the chemical equation the number of atoms of each element is the same on the reactants and on the products side.
Sodium atoms - 1
Hydrogen atoms - 5
Carbon atoms - 3
Oxygen atoms - 5
