First, we need to calculate the amount of energy released when 16.2 g of steam is condensed at 100°C and cooled to 0°C:

1. Energy released from condensation:
16.2 g x 2258 J/g = 36,549.6 J

2. Energy released from cooling:
16.2 g x 4.18 J/g°C x 100°C = 6771.6 J

Total energy released = 36,549.6 J + 6771.6 J = 43,321.2 J

Next, we need to calculate how much ice can be melted by this energy:

1. Melting 1 g of ice requires 333 J of energy.

2. Therefore, the amount of ice melted = energy released / 333 J/g

= 43,321.2 J / 333 J/g

= 130 g

Therefore, the answer is choice C) 130 g.
