It's 50. The popsicles don't lose mass because they are frozen or not frozen.
A pan of ice that has a mass of 100 grams has a mass of 100 grams when it is melted and when it is boiled and turned into steam.
To determine the mass of unfrozen popsicles, we need more information about the freezing process. The mass of frozen popsicles alone does not provide sufficient information to determine the mass of unfrozen popsicles. Please provide additional information or clarify the question.
