In an experiment to determine the density of plasticine, a student records the mass m and the volume V of a range of differently-sized samples. These readings areplotted on a graph as shown. Determine the gradient G of the line and hence the density ρ of the plasticine using the equation ρ = 1/G. Enter your value for ρ to 3 s.f. in the space provided below, ignoring the unit (g/cm^3).

If the density of an object is 2.87 x 10^-3 lbs/cubic inch, what is its density in g/mL? Express your answer in scientific notation rounded to 2 decimal places. You may use the following conversion factors: 1 lb = 454 g, 1 inch = 2.54 cmType ONLY NUMERIC ANSWER (without units). Use "x" sign for multiplication, and "^" sign to type the exponent term, while leaving no spaces in between (to earn computer credit).

The density of a substance is calculated by:

The density of a substance is 676.68 kg/m3. Convert the density to g/cm3.Group of answer choices67668 g/cm36.77 g/cm30.677 g/cm367.7 g/cm3

The density of a material in SI units is 128 kg m-3. In certain units in which the unit of length is 25 cm and the unit of mass is 50 g, the numerical value of density of the material is

A piece of metal has a mass of 60 g and a volume of 3 cm^3, what is the density of the metal?
