Question

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

Answer 1

Answer:

a) $M=VD$

b) m= 6.012g

Step-by-step explanation:

a) We know $D=\frac{M}{V}$. To solve for m, it can be rewritten as $M=VD$

b) Given the density of pyrite is 5.01g/cm^3 and volume of 1.2cm^3, plug into the formula. Solve for M (mass) by multiplying V (volume) and D (density)

$M=({1.2cm^3})(5.01g/cm^3)$

$M=6.012g$

The mass of pyrite is 6.012g not accounting for sig figs.

Answer 2

Step-by-step explanation:

a. d = m/v

m = d × v

b. m = d × v

= 5.01g/cm × 1.2cm

= 6.012g

hopefully this makes sense
