Two substances, A and B, initially at different temperatures, come into contact and reach thermal equilibrium. The mass of subst

ance A is 6.27 g and its initial temperature is 20.9 ∘C . The mass of substance B is 26.1 g and its initial temperature is 52.7 ∘C. The final temperature of both substances at thermal equilibrium is 46.3 ∘C.
If the specific heat capacity of substance B is 1.17 J/(g⋅∘C), what is the specific heat capacity of substance A?

<h3>Answer:</h3>

                  0.64 Moles of Propane

<h3>Explanation:</h3>

Data:

         Moles of Carbon  =  1.5 mol

         Conversion factor  =  7 mol C produces = 3 mol of Propane

Solution:

             As we know,

                7 moles of Carbon produces =  3 moles of Propane

Then,

            1.5 moles of Carbon will produce  =  X moles of Propane

Solving for X,

                     X =  (1.5 moles × 3 moles) ÷ 7 moles

                     X  =  0.6428571 moles of Propane

Or rounded to two significant figures,

                     X =  0.64 Moles of Propane

The cube has a mass of 72.9 g.<br><br> What is its density in g/cm3? <br><br> What substance is it?
sashaice [31]
If the cube is 3 cm on each side, then it has a volume of 27 cm^3 (3 x 3 x 3). Density is mass divided by volume, so its density is 72.9/27 = 2.7 g/cm^3. 

<span>Going by the density, the cube is made of Aluminium - density is a fairly unique quantity</span>
