Marble Density Lab

Density of aqueous solutions of organic acids changes in density of aqueous solutions with changes in concentration at 20 c.

Marble density lab.

The densities of various substances are given in table 1. At 25 2 c 77 36 f or 298 35k at standard atmospheric pressure in imperial or us customary measurement system the density is equal to 100 pound per cubic foot lb ft or 0 926 ounce per cubic inch oz inch. Stop the timer when the marble touches the bottom of the cylinder. Simultaneously drop the marble and start the stopwatch.

Repeat the experiment 2 more times for each liquid so there is enough data to take an average.

Marble hard bulk weighs 1 602 gram per cubic centimeter or 1 602 kilogram per cubic meter i e. 006 sample laboratory report.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. At 25 2 c 77 36 f or 298 35k at standard atmospheric pressure in imperial or us customary measurement system the density is equal to 169 2 pound per cubic foot lb ft or 1 567 ounce per cubic inch oz inch. Record the name of the liquid you tested the original height of the liquid and how long it took for the marble to fall in seconds.

Because of this the density is often used to identify unknown substances or to determine the percent composition. Density is a basic physical property of a homogeneous substance. Mayleen mori jeffrey joseph mary robert and lynnleen albert. The densities of rocks and minerals are normally expressed as specific gravity which is the density of the rock relative to the density of water.

Introduction to density introduction the purpose of this experiment is to understand the meaning and significance of the density of a substance. Density of marble hard bulk is equal to 1 602 kg m. This laboratory explored the relationship between the volume of a marble in cm and the mass of a marble in grams. It is an intensive property which means it depends only on the substance s composition and does not vary with size or amount.

Lesson 2 the nitty gritty of density by teresa kennedy page 14 16 density station data sheet page 17 liquid layers lab sheet page 18 lesson 3 wet goes up must come down by cory patterson page 19 21 wet goes up must come down lab data sheet page 22 lesson 4 density is in the air by tiffany teresa and cory page 23 26. Density of marble solid is equal to 2 711 kg m. This isn t as complex as you may think because water s density is 1 gram per cubic centimeter or 1 g cm 3. Density of acetic acid citric acid formic acid d lactic acid oxalic acid and trichloroacetic acid in water is plotted as function of wt mol kg water and mol l solution.
