Final answer:

The average mass of 1 unpopped popcorn kernel is 0.11 g when rounded to two significant figures, calculated by dividing the total mass before popping (6.0 g) by the number of kernels (55).

Step-by-step explanation:

To calculate the average mass of 1 kernel of unpopped popcorn when given that 55 kernels have a mass of 6.0 g before popping, we must simply divide the total mass by the number of kernels.

Average mass of 1 unpopped kernel = Total mass of kernels / Number of kernels = 6.0 g / 55 kernels.

Performing the calculation:

Average mass of 1 unpopped kernel = 0.1091 g

However, we must consider the precision of our measurements. Since the mass is given to 2 significant figures, our final answer should be rounded to reflect this precision. Thus, the average mass of 1 unpopped popcorn kernel to two significant figures is 0.11 g.
