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

Answer:

The answer is

155 g

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

Hope this helps you

Answer 2

Answer:

$\boxed {\tt 155 \ grams}$

Explanation:

The formula for density is:

$d=\frac{m}{v}$

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

$d*v=d=\frac{m}{v}*v$

$d*v=m$

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.
