A girl measures the mass of a 8 cm3 block of sugar to be a 12.9 g. What is the density of the brown sugar. Give work.

1.61 g/cm³

Step-by-step explanation:

Density is measured as the mass divided by the volume:

d = m / v, where d is the density, m is the mass, and v is the volume

Here, our mass is 12.9 g and our volume is 8 cm cubed, so plug these in:

d = m / c

d = 12.9 g / 8 cm³

d = 1.6125 ≈ 1.61 g/cm³

The density is 1.61 g/cm³.

Density: 1.6g/cm^3

Step-by-step explanation:

Density = mass/volume

Mass: 12.9g

Volume: 8cm^3

12.9/8 = 1.6125

Rounded to tenths place.

1.6 grams/cm^3
