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>
