2. The boiling point of a solution containing 6.4 g of the hormone adrenaline in 360 g of CCl4 is 0.49 K higher than the boiling point of pure CC14. Calculate the molar mass of
adrenaline. (K = 5.02 kg K/mol).​

MM = 182.13g/mol

Explanation:

Hello!

In this case, since the boiling point elevation is computed via:

Thus, since adrenaline is nonionizing, we can compute the molality at first instance:

Now, we compute the the moles of adrenaline in 360 g (0.360 kg) of CCl4:

Finally, the molar mass:

Best regards!

the answer is b & c i believe : )
