Question

Bromine has a density of 3.10g/cm3. If you have 50.0 ML of bromine, how many grams do you have?

Answer 1

`\boxed {\tt 155 \ grams}`

Step-by-step explanation:

The formula for density is:

`d=(m)/(v)`

Rearrange the formula for mass, m. Multiply both sides by v.

`d*v=d=(m)/(v)*v`

`d*v=m`

Mass is found by multiplying the mass by the volume.

The density of the bromine is 3.10 grams per cubic centimeter. The volume is 50 milliliters. Since a milliliter is equal to a cubic centimeter, the volume is also 50 cubic centimeters.

`d= 3.10 \ g/cm^3`

`v= 50 \ cm^3`

Substitute the values into the formula.

`m=d*v`

`m=3.10 \ g/cm^3 *50 \ cm^3`

Multiply. Note the centimeters cubed will cancel out.

`m=3.10 \ g * 50`

`m= 155 \ g`

The mass of the bromine is 155 grams.

Answer 2

The answer is

155 g

Step-by-step explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume of bromine = 50 mL

density = 3.10 g/cm³

It's mass is

mass = 50 × 3.10

We have the final answer as

155 g
