Answer : The mass of sodium chloride is, 8.64 grams
Explanation : Given,
Volume of sodium chloride = [tex]4cm^3[/tex]
Density of sodium chloride = [tex]2.16g/cm^3[/tex]
Formula used :
[tex]\text{Density of }NaCl=\frac{\text{Mass of }NaCl}{\text{Volume of }NaCl}[/tex]
Now put all the given values in this formula, we get mass of sodium chloride.
[tex]2.16g/cm^3=\frac{\text{Mass of }NaCl}{4cm^3}[/tex]
[tex]\text{Mass of }NaCl=8.64g[/tex]
Therefore, the mass of sodium chloride is, 8.64 grams
