The density of liquid ethanol in g/cm³ as a function of temperature T in degrees Kelvin has been
correlated via the equation $\rho$ = 1.032 - 5.392$\times10^{-4}$T - 8.712$\times10^{-7}$T². The equation is dimensionally
homogenous. However, we want to calculate the density in SI units i.e., kg/m³. Then the value of
1.032 in the new equation is _____. Note that 1 Btu = 1055 J, 1 ft = 0.3048 m, 1°R = (9/5) K.
Hint: Use the conversion 1 g/cm³ = 1000 kg/m³
