You have 50.0 mL of pure water and in this you dissolve 24.0 g of sugar. You then add this to 80 mL salt water with a density of 1.25 g/cm3. What is the overall density of the sugar-salt solution?
1.the mass of the salt solution:
"m=\\rho\\times V=1.25\\times80=100" g
the mass of the pure water:
"m=\\rho\\times V=1.00\\times50=50" g
the mass of the sugar solution:
50+24=74
2.The mass of the sugar-salt solution
74+100=174
3.the volume of the salt solution:
"V=80"
the volume of the pure water
"V=50"
the volume of the sugar solution:
"V=\\frac{m}{\\rho}=\\frac{74}{1.587}=46.63"
4.What is the volume of the sugar-salt solution
46.63+80=126.63
density of the sugar-salt solution:
"\\rho=\\frac{m}{V}=\\frac{174}{126.63}=1.37"
