What else can I help you with?
What property depends on the amount of matter in the sample?
Depends on what the sample is and how much of it you have.
A sample of seawater has a mass of 158 grams and a volume of 156ml what is its density?
Divide 158 by 156. The answer is the density in grams per ml. In this case, very close to 1 g/ml Density = MASS divided by VOLUME
Is temperature an extensive or intensive property?
An intensive physical property does not depend on the size of the sample. An example of an intensive physical property is density. An extensive physical property does depend on the size of the sample, such as mass and volume.
What equipment and materials will you use in separating insoluble materials from seawater?
You can filter it off using a sinted glass crucible, fine filter paper, a vacuum pump and a side-arm flask. If you don't have that sort of equipment: a filter funnel, filter paper and a conical flask should do.
Why is iodine considered a trace element in seawater?
A trace element is considered is a specific element that contains less than 100 parts per million in a sample. In this case, the sample is seawater. According to my understanding, the presence of iodine is very limited in seawater. There is only 0.05 parts per million of iodine in seawater. As such, iodine is considered a trace element in seawater.
Why for gel filtration chromatography the smaller the sample volume the better the separation?
in gel filtration the volume of eluent is what moves compounds in and out of the pores in the matrix.A large volume of sample means the sample components will not be introduced to the matrix as a tight "plug" and the sample will slowly spread into the matrix meaning the beginning and the ending of the sample will be far apart meaning the sample will be spread out over the gel matrix resulting in poor resolution of that component from any other.
Could you use filtration to seperatesalt from water in a sample of seawater?
Yes, some filters allow this. Some pressure must be aplied, to counteract the osmotic pressure. For more information, do some reading on reverse osmosis.
What is the mass of a 600 ml sample of seawater with a density of gm?
To calculate the mass of a 600 ml sample of seawater, you need to know the density. If the density of seawater is approximately 1.025 g/ml, the mass can be calculated using the formula: mass = density × volume. Therefore, the mass of the seawater would be approximately 600 ml × 1.025 g/ml = 615 grams.
What is The best way to remove the mud from a sample of lake water?
Filtration

Why crystals disappear during suction filtration of a sample crystallized from benzene?
Crystals may disappear during suction filtration of a sample crystallized from benzene if the crystals dissolve in the solvent being used for filtration, or if they break up into smaller particles that pass through the filter. This can happen if the crystals are not fully dried or if too much force is applied during filtration.
Why cant mass used as a property to identify a sample of matter?
Mass is an extensive property, which depends only on the amount of matter in the sample, not on the composition of the sample.
What is the separation techniques for sublimation?
The technique is simple: heating of the sample.
A sample of seawater weighs 158 g and has a volume of 156 mL What is the density?
It is 1.0128 g/mL.
Seawater is not a substance because?
Seawater is not a substance in the traditional sense because it is a mixture of various substances including water, salts, minerals, and organic matter. These components can vary in concentration and composition depending on the location and conditions of the water.
Sample of mixture that can be separated by distillation?
A type of Mixture in which Solute and Solvent Both are liquid can be separated by Distillation. It is done on the basis of their boiling point and if boiling point is below 25 C then fractional distillation is done.
