After 20 minutes, the mass of the liquid water can be calculated by subtracting the remaining mass of ice from the initial total mass of ice and water. Initially, there was 400 grams of liquid water and 75 grams of ice. Since the mass of the ice decreased to 50 grams, that means 25 grams of ice melted (75g - 50g), which means there are now 400g + 25g = 425 grams of liquid water.
A 50 gram glass holds 400 grams of liquid water and 75 grams of ice. After 20 minutes the mass of ice is 50 grams. In 1-2 sentences, assuming no evaporation or sublimation has occurred, calculate the mass of the liquid water at this time and explain how this is found.(2 points)
