Question #264207

What volume of alcohol with the density 8.4*100 will have the same mass as 4.2m of petrol whose density is 7.2*100

Expert's answer

The mass of 4.2 m³ of petrol:

"m=\\rho_p V_p=720\u00b74.2=3024\\text{ kg}."

The volume of alcohol for the same mass of alcohol:

"V_a=m\/\\rho_a=3024\/840=3.6\\text{ m}^3."
