Question

Severus Snape knows that density of his powder is 3.00 g/cm3 . He also knows he needs 3.00 cm3 of this powder. What mass in grams does he require?

Answer 1

He requires 1 gram of mass.

Step-by-step explanation:

The density is defined as:

`\rho = (m)/(V)` (1)

Where m is the mass and V is the volume.

Then, m can be isolated from equation 1 in order to determine the mass.

`m = \rho \cdot V` (2)

`m = (3.00g/cm^(3))(3.00cm^(3))`

`m = 1g`

Hence, he requires 1 gram of mass.
