Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution
1 C4H8 + 6 O2 = 4 CO2 + 4 H2O
Well density is mass divided by volume. As an object expands, its mass remains the same while the volume increases. This means that you will be dividing the same mass by a larger number which will result in a smaller final number or density.
The specific heat capacity of the metal is determined as 0.76 J/g⁰C.
<h3>Mass of the water</h3>
mass = density x volume
mass = 342 ml x 1 g/ml = 342 g
<h3>Specific heat capacity of the metal</h3>
Apply the law of conservation of energy;
Heat lost by the metal = Heat gained by the calorimeter + heat gained by water
(93.4)(85 - 29.3)c = (8.29)(29.3) + (342)(4.186)(29.3 - 26.7)
5,202.38c = 3,965.088
c = 3,965.088/5,202.38
c = 0.76 J/g⁰C
Thus, the specific heat capacity of the metal is determined as 0.76 J/g⁰C.
The complete question is below;
93.4 g of a metal is heated to 85.0 C in a hot water bath, then dropped into a calorimeter containing 342 ml of water (d 1.00 g/mL) at 26.7 . The equilibrium temperature was found to be 29.3 C. Calculate the specific heat of the metal with proper units. (C.cal 8.29 J/c)
