Answer: 2.02 J/g°C

Explanation:

To find the heat capacity, we have to manipulate the equation for heat.

q=mCΔT becomes C=q/(mΔT) to find heat capacity. Since we are given our values, we can plug in to find C.

C=\frac{47.2J}{13.4g*1.74°C}

*Please ignore the capital A in front of the °C. In order to have ° in the equaiton, the A pops up.

C=2.02J/g°C

What is the concentration of a 0.750 l solution that contains 52.0 g of glucose (c6h12o6)?
vodka [1.7K]
Concentration of Solutions is oftenly expressed in Molarity. Molarity is the number of moles of solute dissolved per volume of solution.

                             Molarity  =  Moles / Volume
As,
      Moles  =  Mass / M.mass
So,
                             Molarity  =  Mass / M.mass × Volume   ---- (1)

Data Given;
                   Volume  =  0.750 L

                   Mass  =  52 g

                   M.mass  =  180 g/mol

Putting Values in eq.1,

                     Molarity  =  52 g ÷ (180 g.mol⁻¹ × 0.750 L)

                     Molarity  =  0.385 mol.L⁻¹
