<span>My hypothesis is the the cell, having a higher osmolarity than the solution of of nacl in the beaker, will have an osmosis reaction releasing into the solution of nacl. This will continue until both cell and solution reach a balance.</span>

Answer:
Mass of the sample = m = 894.0 g
Initial temperature of the sample = T_i=-5.8^oC=267.35 KT
i
=−5.8
o
C=267.35K
Final temperature of the sample = T_f=17.5^oC=290.65 KT
f
=17.5
o
C=290.65K
Change in temperature = \Delta T=(T_f-T_i)ΔT=(T
f
−T
i
)
Specific heat capacity of the substance = c
Heat required to raise the temperature of a 894.0g sample = Q
Q = 4.90kJ = 4900 J
Q=m\times c\times \Delta T=m\times c\times (T_f-T_i)Q=m×c×ΔT=m×c×(T
f
−T
i
)
4900 J=894.0 g\times c\times (290.65 K-267.35 K)4900J=894.0g×c×(290.65K−267.35K)
c=0.23523 J/g K\approx 0.235 J/g Kc=0.23523J/gK≈0.235J/gK
The chemist will report the specific heat capacity of the substance as 0.235 J/g K.
