Multiply the volume with density

Density essentially gives the mass of the material per unit volume.

Here density is given as 1.03g/c#m^3#

Which means 1c#m^3# volume of water has a mass of 1.03 gram

Here the volume of water tank is 1890 L

1 Liter = #10^-3# #m^3#

Mass of 1890 x #10^-2# #m^3# = (1.03g / #10^-2# #m^3#) x( 1890 x #10^-2# #m^3#)

Mass = 1946.7 Kg
