What is the denisty of benzene at 65.8mL...? help!?
-
The density of benzene at 15 C is .8787 g/mL. Calculate the mass of .1500L of benzene at this temperature? What are the steps to do this? Also.... The density of titanium metal is 4.51g/cm3 at 25 C. what mass of titanium displaces 68.8mL of water at 25 C?

Answer:
Density is basically given as the amount of grams per mL in the question. The density of benzene states that for every 1 mL you have .8787 g benzene. Then it gives you the volume(.1500 l). First, you must convert this to mL: .15 * 1000 = 150 mL Then multiply by .8787 g to get the total mass: .8787g * 150 mL = 131.8g benzene For the second problem, you dont even need to convert: 68.8 mL * 4.51 = 310.3 g titanium

MASS = VOLUME x DENSITY now do the benzene problem yourself. DISPLACEMENT is a volume consideration. The mass will have a volume of 68.8 cc. So again, MASS = VOLUME x DENSITY.

mass = density x volume
