Milan is measuring the density of ethanol. He weighs a bottle three times:
first, empty; then filled with water; then filled with ethanol. Here are his
results:
mass of empty bottle = 30.0g
mass of bottle filled with water = 90.0g
mass of bottle filled with ethanol = = 78.0g
i Calculate the volume of the bottle.

Respuesta :

  • Mass of ethanol=78-30=48g
  • Density of ethanol=0.789g/cm^3

[tex]\\ \tt\hookrightarrow Density=\dfrac{Mass}{Volume}[/tex]

[tex]\\ \tt\hookrightarrow Volume=\dfrac{Mass}{Density}[/tex]

[tex]\\ \tt\hookrightarrow volume=\dfrac{48}{0.789}[/tex]

[tex]\\ \tt\hookrightarrow Volume=68.83cm^3[/tex]

Xignerso

Density of ethanol[tex]=0.789g/cm^3[/tex]

Mass of ethanol[tex]=78-30=48g[/tex]

[tex]Density = \frac{Mass}{Volume} [/tex]

[tex]Volume = \frac{Mass}{Density}[/tex]

[tex]Volume = \frac{48}{0.789}[/tex]

[tex]Volume = 68.83cm³[/tex]
