volume of material with mass of 4.00g & a density of 7.40g/mL

Answer 1

We can manipulate the units given to find the volume of an unknown material given the mass, in units of grams, and the density, in units of grams per milliliter, of the material.

Volume has units of mL as well as L. We will need to use stoichiometry to have an end unit of just mL from the given values.

Our conversion factor will be the density value of 7.40 grams per 1 milliliter.

Our starting value or amount will be 4.00 grams of the material.

There are 3 significant figures in both the density value and the mass value given. We will be using multiplication/division to solve the problem therefore, 3 significant figures will be how we present the final answer.

4.00 g x 1 mL = 0.54054 mL material = 0.541 mL material

1 7.40 g
