Answer :
Answer: The mass of salt water is 390 grams
Explanation:
To calculate the mass of salt water, we use the equation:
[tex]\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}[/tex]
Density of salt water = [tex]1.30g/cm^3[/tex]
Volume of salt water = 300 mL = [tex]300cm^3[/tex] (Conversion factor: [tex]1mL=1cm^3[/tex] )
Putting values in above equation, we get:
[tex]1.30g/cm^3=\frac{\text{Mass of salt water}}{300cm^3}\\\\\text{Mass of salt water}=(1.30g/cm^3\times 300cm^3)=390g[/tex]
Hence, the mass of salt water is 390 grams
