Question

A 500g sample of an element undergoes a phase change, and 57.2g of ice melts. What is the remaining mass of the element?

A. 442.8 g

B. 442.0 g

C. 442.2 g

D. 443.2 g

Answer 1

After 57.2g of ice melts from a 500g sample, the remaining mass of the element is 442.8g.

Step-by-step explanation:

The student's question is about the mass remaining after part of a sample undergoes a phase change. If you start with a 500g sample of an element and 57.2g of ice melts, the mass that remains is simply the original mass minus the mass of the ice that melted. The calculation is as follows: 500g - 57.2g = 442.8g. Therefore, the remaining mass of the element is 442.8g.
