QUESTION ①)</u></h3>
✔ C5H4 has a molecular molar mass of :
<em>M(C5H4) = 5 x M(C) + 4 x M(H) </em>
- M(C5H4) = 5 x 12 + 4 x 1
- M(C5H4) = 60 + 4
- M(C5H4) = 64 g/mol
✔ The molecular mass of C5H4 is therefore 64 g/mol.
<h3>This is double the molar mass of C5H4, this molecule has the formula 2C5H4.</h3>

Answer:
Importance of Phlogiston Theory . Although the theory has since been discarded, it's important because it shows the transition between alchemists believing in the traditional elements of earth, air, fire, and water, and true chemists, who conducted experimentation that led to the identification of true chemical elements and their reactions.
