The liquid iodobenzene has a density of 1.83 g/mL at 20.0 °C. If a 56.4 mL sample of this compound is provided, what is the mass of the liquid at 20.0 °C that must be provided? Mass=...........g

A bulk sample is the physical sample of a large volume or tonnage of mineral material taken from a known resource area for investigative purposes.Primary sampling unit refers to Sampling...

V = m/d = 2.38g/(0.718g/cm3) = 3.315 cm3

m = mcompound * W m(Cu) = 160 g * 0.799 = 127.84 g M(S) = 160 g * 0.201 = 32.16 g.

density = m / V0.0496 dm3 = 49.6 mlm = density x V = 0.85 x 49.6 ml = 42.16 g

69.22lb/ft3=1.1088 g/mL.Therefore the unknown liquid is ethylene glycol.

One mole of an ideal gas will occupy a volume of 22.4 liters at STP (Standard Temperature and Pressure, 0°C and one atmosphere pressure).Proportion:1 mole – 22400 mln moles –...

mass 33.4 kg

Volume = Mass / Density = 143g / 1.62g/mL = 88.27mL

volume = 72,22 ml
