V = 3 x 1 x 1.5 = 4.5 cm^3
m = d x V
= 19.32 x 4.5
= 86.94g
Answer:
As the temperature of the water increases, the time needed for the dye to spread decreases. This is because the kinetic energy between the liquid particles increases, therefore helping the dye to dissolve and spread throughout the water.

Answer:
You would need 85.5 g
Explanation:
Molarity=Moles of soluteVolume of solution (in litres)0.25 M=n1 Ln = 0.25 molSo, we need 0.25 mol of sucrose to make 0.25 M solution.Molar mass of sucrose (C12H22O11)=342 g/mol Mass of 0.25 mol sucrose is0.25mol×342gmol=85.5 g
