Question

The enthalpy of combustion of benzene ( 1 ) is - 3264.6 kJ mol - ¹ . What mass of benzer is required liberate 1632.3 kJ of heat upon its combustion?​

Answer 1

Answer:

The density of a material in the shape of a cube is determined by measuring three sides of the cube and its mass. If the relative errors in measuring the mass and length are respectively 1.5% and 1%, the maximum error in determining the density is: 3.5%
