Calculate the density of an acid if 138.4 mL of the avid weighs 16.14g

Sagot :

Answer:

[tex]0.12g/cm^3[/tex]

Explanation:

Firstly, you should use this formula :

[tex]Density=\frac{mass}{volume}[/tex]

We know the mass is 16.14g, and volume as [tex]138.4ml[/tex].

Also remember to convert [tex]ml[/tex] to [tex]cm^3[/tex], where [tex]1ml = 1cm^3[/tex]

Therefore, [tex]138.4ml=138.4cm^3[/tex].

Substitute the value :

[tex]\frac{16.14g}{138.4cm^3}=0.1166g/cm^3[/tex]

Rounding it to 2 significant figure :

[tex]0.12g/cm^3[/tex]
