Practice makes perfect

a To solve the formula for m, let's isolate m on one side.

d=m/V

MultEqn

LHS * V=RHS* V

dV=m

RearrangeEqn

Rearrange equation

m=dV

b The density of the pyrite is given as 5.01 g/cm^3 and its volume 1.2 cm^3. In order to find the mass m, we substitute these values into the rewritten formula.

m=dV

SubstituteII

d= 5.01, V= 1.2

m= 5.01 * 1.2

Multiply

m=6.012

Therefore, the mass is 6.012 grams.
