What is the volume percent concentration of hexane in a solution made by mixing 50.0 mL of hexane with 1.0 L of pentane?
To calculate the volume percent concentration of hexane in the solution, you need to determine the total volume of the solution first. Mixing 50.0 mL of hexane with 1.0 L of pentane gives a total volume of 1.05 L (1000 mL + 50 mL). The volume percent concentration of hexane can be calculated as (volume of hexane / total volume) x 100. This gives (50 mL / 1050 mL) x 100 = 4.76% volume percent of hexane in the solution.
Hexane is an organic solvent that has a density of 0.6603 g cm at 20c if hexane is mixed with water there is a separation of the two solvents into two layers why did this separation occur which solven?
The separation occurs because hexane is nonpolar and water is polar, leading to immiscibility. Hexane molecules are attracted to each other and repelled by water molecules, causing them to form a separate layer. This phenomenon is due to differences in intermolecular forces between the two solvents.
Do molecules have anything to do with volume?
Yes, molecules play a role in determining the volume of a substance. The number and size of molecules in a substance affect its density, which in turn influences its volume. Additionally, the packing arrangement of molecules in a substance can determine its overall volume.
Which has greater volume 10g of hexane or 10g of toluene?
To calculate volume out of mass you'll need the density figures of both compounds:Hexane 0.6548 g/mLToluene 0.8669 g/mL (20 °C)Volume of 10.0 grams: (divide mass (g) by density (g/mL) )Hexane 10 g / 0.6548 g/mL = 15.27 mLToluene 10 g / 0.8669 g/mL = 11.54 mLSo, the volume of (10 g) hexane is 32% greaterthan of the same amount of toluene
Which has greater volume 10g chloroform or 10g hexane?
10g of chloroform has a greater volume than 10g of hexane because chloroform has a higher density than hexane. Density is a measure of mass per unit volume, so for the same mass, the substance with the higher density will occupy less volume.

Why is hexane burned?
Hexane is only burned when it is used as an additive in gasoline. Hexane is highly flammable and can cause an explosion so there is only 1 percent to 3 percent of hexane in the total volume of gasoline. Hexane is a chemical used as a solvent to make vegetable oil from various sources, like soybeans.

What factors determine density?
The factors that determine density include the mass and volume of a substance. Density is calculated by dividing the mass of an object by its volume. Different substances have different densities based on how closely packed their molecules are. Temperature and pressure can also affect the density of a substance.
5.0 times 10 to the 24th power molecules is how many liters?
To convert molecules to liters, you need to know the volume of one mole of the substance. For water, 1 mole contains about 18.01528 grams, which is approximately 18.01528 ml. Knowing there are 6.022 x 10^23 molecules in a mole, you can calculate the volume for 5.0 x 10^24 molecules.
