The density of lead is 11.3 g/ml. the water level in a graduated cylinder initially at 215 ml rises to 285 ml after a piece of lead is submerged. what is the mass, in grams, of the lead?

Respuesta :

Answer: 791 g

Given:

Initial volume, [tex]V_1=215mL[/tex] (when only water is present.

when lead is added

Final volume, [tex]V_2=285mL[/tex]

Denisty of lead = 11.3 g/mL

Formula Used:

Mass= Density[tex]\times[/tex] volume

Volume of lead, [tex]V= V_2-V_1\\ \Rightarrow V=285-215 =70mL[/tex]

Mass of lead =11.3g/mL[tex]\times[/tex]70mL=791g
