What is the density of water if you have 50.0 grams of water and a volume of 50.0 millimeters

Gnom [1K]

Answer:

$\boxed {\tt 1.0 \ g/mL}$

Explanation:

Density can be found by dividing the mass by the volume.

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

The mass of the water is 50.0 grams.

The volume of the water is 50.0 milliliters.

$m= 50.0\ g \\v=50.0 \ mL$

Substitute the values into the formula.

$d=\frac{50.0 \ g}{50.0 \ mL}$

Divide.

$d= 1.0 \ g/mL$

The density of the water is 1.0 grams per milliliter. Also, remember that the density of pure water is always 1.0 g/mL or g/cm³
