MakcuM [25]

Answer:

33.8.

Explanation:

Hello,

In this case, since the used equation is:

Q=mCp(T_2-T_1)

Whereas the specific heat is 4.184 J/(g°C), we compute the mass as follows:

m=\frac{Q}{Cp(T_2-T_1)}

Thus, the mass turns out:

m=\frac{3,710J}{4.184\frac{J}{g\°C} (48.9-22.7)\°C}\\\\m=33.8g

And without units:

33.8.

Best regards.

BaLLatris [955]

Answer: The density of the liquid is 1.10g/cm^3

Explanation:

Density is defined as the mass contained per unit volume.

Density=\frac{mass}{Volume}

Given : Mass of the unknown liquid  = 938 grams

Volume of the unknown liquid = 0.852L=852cm^3  (1L=1000cm^3

Putting in the values we get:

Density=\frac{938g}{852cm^3}

Density=1.10g/cm^3

Thus the density of the liquid is 1.10g/cm^3 and the liquid is dimethyl sulfoxide.
