A gold chain with a mass of 40 grams is placed into a graduated cylinder. The graduated cylinder had a volume of 30 ml before the chain was placed in graduated cylinder. After it was added to the graduated cylinder the volume had risen to 50 ml. What is the density of the chain?
Just kidding it's 20 mL
To find the density of an object, you need to divide its mass by its volume. In this case, the mass of the gold chain is given as 40 grams, and the volume change in the graduated cylinder when the chain was added is 50 ml - 30 ml = 20 ml.
To calculate the density, you would divide the mass (40 grams) by the volume (20 ml):
Density = Mass / Volume
Density = 40 grams / 20 ml = 2 grams/ml
Therefore, the density of the gold chain is 2 grams/ml.
