Question

The density d of a substance is given by the formula d=mV, where m is its mass and V is its volume.

a. Solve the formula for m.
b. Find the mass of the pyrite sample.
(Explain how you found the answer so hopefully I can try the next question like this.)

Answer 1

To find the mass (m) of a substance based on its density (d) and volume (V), rearrange the density formula to m = d * V. Substitute the known values of density and volume into this formula to calculate the mass.

Step-by-step explanation:

The student needs help with rearranging a formula used in density measurement and calculating the mass based on the given density and volume. First, we solve for m by rearranging the density formula:

Original formula: d = m / V

To find m, multiply both sides by V:

m = d * V

Next, to find the mass of the pyrite sample, we use the rearranged formula. If the density and volume of the pyrite are known, we simply substitute these values into the formula to calculate its mass.

For example, if the pyrite has a density of 5 g/cm³ and a volume of 2 cm³:

m = 5 g/cm³ * 2 cm³ = 10 grams
