Answer:
To determine the mass of an object that has a volume of 23.0 ml and a density of 0.788 g/cm3, we can use the equation:
mass = density x volume
First, we need to convert the volume from milliliters to cubic centimeters (cm^3) since the density is given in g/cm^3.
1 mL = 1 cm^3
so
volume = 23.0 ml = 23.0 cm^3
Next, we can substitute the density and volume into the equation above:
mass = 0.788 g/cm^3 x 23.0 cm^3 = 18.204 g
Therefore, the mass of the object is 18.204 grams.
