The density of mercury is 13.54 g/cm3. Suppose you need 40 gm of mercury for an experiment. What volume of mercury do you need?

mass = volume x density

541.6 To find the volume of mercury needed for the experiment, we can use the equation:

Volume = Mass / Density

Given that the mass of mercury needed is 40 g and the density of mercury is 13.54 g/cm3, we can substitute these values into the equation:

Volume = 40 g / 13.54 g/cm3

First, we need to convert the density of mercury from g/cm3 to g/mL since the mass is given in grams and we want the volume in milliliters. Since 1 cm3 is equal to 1 mL, we can conclude that 1 g/cm3 is equal to 1 g/mL.

Now we can substitute the values:

Volume = 40 g / 13.54 g/mL

Dividing 40 g by 13.54 g/mL gives us the volume in milliliters:

Volume = 2.95 mL

Therefore, for the experiment, you will need approximately 2.95 mL of mercury.
