Answer:

18 times

Explanation:

Heart rate = 0.3 cycles/s

Heart rate = [tex]\frac{number of cycles}{time}[/tex]

number of cycles = heart rate x time

But, 1 min = 60 seconds

⇒ number of cycles = 0.3 x 60

                                  = 18

Thus, the number of times that the Mollusk's heart beat in 1 min is 18.
