10. It is estimated that if the entire Greenland ice sheet melted, global sea level would increase by 20 feet. a) Assuming this estimate is accurate, estimate the current volume of the Greenland ice sheet, in cubic kilometers. [5 pts] b) In a hypothetical future "hydrogen economy", hydrogen would be extracted from water to act as an "energy carrier" for use in hydrogen fuel cells. How many hydrogen atoms are contained in the water in the Greenland ice sheet? [5 pts)

Answer 1

here I have collected two data from Wikipedia as water surface area is 360 million square kilometers and for better calculation assumed that density of water and ice equal.
