Answer:
A
Explanation:
A hypertonic solution is one in which the concentration of the solute is greater than that of those inside the cell. This means that there is a solution with a higher concentration of solute compared to what is obtainable inside the cell environment.
Hence, we say that the solutions are hypertonic since they contain essentially solutes that are more concentrated than those inside the cell
Answer
Q = mcΔT
Qwater = -Qmetal
(100 g)(4.18 J/g°C)(25°C - 20°C) = -(50 g)c(25°C - 90.0°C)
2090 J = (3250 g °C)c
c = 0.643 J/g °C
