Question

Answer keeps getting marked wrong! need some guidance..

what is the mass in grams of 8000. mL of alcohol is the density of 0.79 g/mL? Use sig figs please

Answer 1

Step-by-step explanation:

The volume of ethanol is V =8000 ml

The density if the ethanol is ρ=0.79g/mL

density = mass/volume which can be rewritten as

mass = density x volume

Using given volume and density, the mass of ethanol is computed

mass = (8000 mL) x (0.79 g/mL)

mass = 6320 g

Thus, the mass of ethanol is 6320 grams.
