The density (g/mL) of a rectangular bar that has a mass of 186.77 g and measures 4.26 cm in length, 1.42 cm in width, and 19.21 cm in height is 1.61g/mL.
The density of a substance can be calculated by dividing the mass of the substance by its volume.
According to this question, a rectangular bar measures 4.26 cm in length, 1.42 cm in width, and 19.21 cm in height.
Volume of rectangular bar = Length × width × height
= 4.26 × 1.42 × 19.21
= 116.21cm³
Density of the bar = 186.77g ÷ 116.21mL
Density of the bar = 1.61g/mL
Therefore, the density (g/mL) of a rectangular bar that has a mass of 186.77 g and measures 4.26 cm in length, 1.42 cm in width, and 19.21 cm in height is 1.61g/mL.
