Question

An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide. if the mass is 21.3 g, what is this substances density (in grams per milliliter)?

Answer 1

Volume of rectangular substance (cm3)=3.6 x 4.21 x 1.17=17.7 cm3
Volume of rectangular substance ( mm3)=17.7 x 1000=17700 mm3 (As moving from bigger to smaller so we multiply and as it is cube so we multiply by 1000)
                                     (1cm=10mm)
density=21.3/17700=0.001203 g/mm3
ANSWER IS 0.001203 g/mm3 density

Answer 2

Answer:

density=1.2g/cm^3

Explanation:

Hello,

Density is defined as the degree of compactness of a substance and is mathematically expressed via the division between the substance's mass and the occupied volume:

$density=\frac{m}{V}$

Thus, the occupied volume is:

$V=3.6cm*4.21cm*1.17cm=17.73cm^3$

Finallt, the computed density:

$density=\frac{21.3g}{17.73cm^3}\\density=1.2g/cm^3$

Best regards.
