The density of the rectangular block is 1.07 g/mL.

From the question, we have the mass of the rectangular block as 121g

The dimensions of the block are given as follows;9.1cm by 5.4cm by 2.3cm

So we have the volume of the block as; 9.1cm × 5.4cm ×  2.3cm = 113 cm^3

Let us recall that; 1 cm^3 = 1 mL, so 113 cm^3 = 113 mL

Having said that, we must also remember that;

Density = Mass/volume

Density = 121g/113 mL

Density = 1.07 g/mL
