An experiment requires 74.2 mL of ethyl alcohol. If the density of ethyl alcohol is 0.790 g/cm3, what is the mass of 74.2 mL of ethyl alcohol?

Solutions

Expert Solution

Density = mass / volume

Given density = 0.790 (g/cm^3)

Volume = 74.2 ml = 74.2 cm^3 ( 1 ml = 1 cm^3)

Therefore mass = density * volume

Mass = 0.790 (g/cm^3) * 74.2 (cm^3 ) = 58.618 g

In a constant-pressure calorimeter, 75.0 mL of 0.790 M H2SO4 was added to 75.0 mL of 0.360 M NaOH. The reaction caused the temperature of the solution to rise from 23.01 °C to 25.46 °C. If the solution has the same density and specific heat as water (1.00 g/mL and 4.184 J/g·K, respectively), what is ΔH for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.
