The water level in a graduated cylinder initially at 210 mL rises to 282 mL after a piece of lead is submerged. What is the mass in grams of the lead?

Question

it is chem i  need help

Answer 1

To answer this, one needs to know the density of lead.

Change in volume = 282 ml - 210 ml = 72 mls

Assuming a density of 11.34 g/ml the mass of the lead would be

72 mls x 11.34 g/ml = 816.5 grams
