Question

Osmium is the most dense element we know of. A 22 g sample of Osmium has a volume of 100 cL. Calculate the density of Osmium in g/mL. *Hint: In order to do this you will first need to convert the volume into mL, and then divide. Grams into mL a. Converted volume. 1 mL = 0.1 cL ---------- b. Density (g/mL) = __________

Answer 1

Answer:

a. V = 1000 mL

b. Denisty = 0.022 g/mL

Explanation:

a.

First we need to convert the volume of the Osmium into mL. For that purpose we are given the conversion unit as:

1 mL = 0.1 cL

Hence, the given volume of Osmium will be:

V = Volume of Osmium = 100 cL = (100 cL)(1 mL/0.1 cL) = 1000 mL

V = 1000 mL

b.

The density of Osmium is given by the following formula:

Density = mass/Volume

Denisty = 22 g/1000 mL

Denisty = 0.022 g/mL
