Question

How many grams of mercury are present in a barometer that holds 6.5mL of mercury? ...?

Answer 1

Answer: The mass of mercury will be 20.15 g.

Explanation:

Density is defined as the mass contained per unit volume.

`Density=(mass)/(Volume)`

Given : Mass of bromine = ?

Density of bromine=
`3.1g/ml`

volume of bromine = 6.5 ml

Putting in the values we get:

`3.1g/ml=(mass)/(6.5ml)`

`mass=20.15g`

Thus the mass of bromine is 20.15 g.

Answer 2

13.6
so grams of mercury present in a barometer that hold
per milliliter.
13.6*6.5 = 88.4
