total mass: 47.27g solid mass: 22.19g so, toluene mass: 25.08g toluene density is .864g/ml, so toluene volume: 25.08g / 0.864g/ml = 29.03ml so, solid volume: 20.97ml solid density: 22.19g/20.97ml = 1.058g/ml

Something to consider in handling of units: 1.00 g/mL = 1 g / 1 mL 1 g / 1 mL = 1000g / 1000mL = 1 kg / L The above steps show that a density of 4.5 g/mL is equivalent to 4.5 kg/L. Using a density of 4.5 kg/L should make it possible to get the volume in directly in liters ...

What in the world are you talking about? 15.8 mg/L x (100 mL/25 mL) = 15.8 mg/L x 4 = 63.2 mg/L. (100 mL/25 mL) is 100 mL DIVIDED by 25 mL and that is 4. The mL of 100 and the mL of 25 cancel to leave a pure number x 15.8 mg/L to leave units of mg/L). The units are mg/L x (mL/...
