Hailey measured the mass of 1 cup of water and found that it was 154g. She then measured the mass of ¼ of a cup of salt and found that it was 53g. She poured the salt into the water and stirred it until she could no longer see the salt. If Hailey measured the mass of the water again after, what should she find?
A. Mass will be 101g B. Mass will be 154g C. Mass will be 207g D. Mass will be 53g
C. Mass will be 207g -> 154 g of Water + 53 g of Salt
