“buy Leads”
I have 2 density problems i HAVE to answer for school help!?
please show work or steps thanks:)
1) the “lead” in a pencil is really graphite which is a form of the element CARBON. Janice cut open a new pencil and measured the mass of the graphite to be 1.8 grams. what is the VOLUME of the graphite in the pencil?
2)Roger the fisherman bought some new LEAD sinkers. He noticed that each one seemed very heavy as he put it in a graduated cylinder. The volume rose from 62mL to 71mL. calculate the MASS of *ONE* lead sinker.
THANKS A LOT!!!! 
1) Density is mass over volume (D = m/v). That means volume is mass over density (v = m/D). They give you the mass, so look up the density of graphite, then divide the mass by the density. Watch your units.
2) This tells you the volume is is 71-62=9 mL. Look up the density of lead. Now that you know the density and the volume, you can find the mass using D=m/v.
