Chemistry Problem?
A chemist has been given a piece of an unusual meteorite for analysis. The meteorite fell into a field 220 km. from the chemist's lab. The meteorite had a mass of 14.9 kg. The piece sent to the chemist is irregular shaped and is 3 cm. long. A scale shows the piece weighs 1.6 newtons. A balance shows it's mass to be 163 g. The chemist decides to determine the volume of the fragmentby seeing how much water it will displace when submerged. The chemist adds water to a graduated cylinder that can hold 50.0 cm3. The level of water in the cylinder shows it contains 25.8 cm3. After the meteorite peice is submerged, the water level rises to 45.9 cm3. the density of water is 1.00 g/cm3. What density will the chemist calculate for the meteorite samples? Organize the information just given into two lists- relevant and irrelevant data. Then carry out the calculation.
irrelevant data:
graduated cylinder can hold 50 cm^3
The meteor fell into a field that is 220 km
the meteor was 14.9 kg
Relevant data:
level of water started at 25.8 cm^3
after adding fragment level of water was 45.9 cm^3
fragment weighs 163 g
Work:
one cm^3 is always one ml
45.9-25.8=20.1
density is mass over volume
163 g/20.1 ml or 8.10945 g/ml
