Answer:
The correct answer is - 27 grams.
Explanation:
salts contain atoms (ions) like Na+ and Cl, these atoms are electrically charged that leads to a big crystal as they can stick together. Those are too heavy to evaporate.
When you heat the hot plate water evaporates but the salt does not leave vessel so, the concentration of salt in the water increases. In the end, the concentration of salt gets so high and the salt will begin to recrystallize into a solid. When all of the water is gone, you will have salt left behind in the same concentration.
Thus, the correct answer is - 27 grams.

Answer:
Mass = 208.26 g
Explanation:
Given data:
Volume of water = 40.0 mL
Volume of water + copper = 63.4 mL
Volume of copper = ?
Density of copper = 8.9 g/cm³
Mass of copper = ?
Solution:
Volume of copper:
Volume of copper = (Volume of water + copper ) - Volume of water
Volume of copper = 63.4 mL - 40.0 mL
Volume of copper = 23.4 mL
Mass of copper:
density = mass/volume
8.9 g/cm³ = mass/23.4 mL
cm³ = mL
Mass = 8.9 g/mL × 23.4 mL
Mass = 208.26 g
