How many grams are in 2.25 moles of hexane?
Molar weight of C6H14 - 6*12 + 14* 1 = 86g Therefore 2.25 moles = 86 * 2.25 = 193.5g
What is the parachor value of hexane by simplification?
The parachor value of hexane can be estimated using its molecular weight and density. Hexane (C6H14) has a molecular weight of approximately 86.18 g/mol and a density of about 0.6548 g/cm³. The parachor value is calculated as the product of the molecular weight and a constant related to the density, resulting in a parachor value of approximately 60.5. This value reflects the cohesive forces in the liquid phase and is useful in characterizing its physical properties.
Would you expect hexane to be soluble in water?
The density of cyclohexane is lower than that of water (0.779 g/mL vs. 1.0 g/mL respectively), so it will float on top of water.
Is ice more dense than hexane?
No, ice is not more dense than hexane. Ice has a density of about 0.92 g/cm³, while hexane has a density of approximately 0.66 g/cm³. This lower density of hexane means that ice will float on hexane when the two are combined.
What mass of oxygen (O2) is required to react completely with 86.17 grams of C6H14?
The answer is 152 g oxygen.
Does sulphur dissolve in hexane?
SOLUBILITY IN WATER Insoluble SOLVENT SOLUBILITY Soluble in hexane, toluene, ethanol and acetone. Insoluble in propylene glycol --- The above statement with water is wrong. I am currently running experiments on equilibrium concentration of succinic acid in a water/hexane system. I was able to find several articles in the litterature where a mixture of succinic acid and n-butanol is used, but nothing with succinic acid and hexane. I estimate the solubility of Succinic Acid in water to be ≥23.020±0.005 g/kg of water @ 21˚C. So far, 0.1g do NOT disolved completely in 133g of hexane, even after being heated to about 35˚C and stirred intensively for several hours. CHG Patrick - 25/08/10 ---- Patrick is absolutely right. The first answer is completely wrong. Succinic Acid is not going to be soluble in hexane as Malonic and Succinic acid are both highly polar substances and Hexane is Non-Polar. Like dissolves like. -Trifectaus Sept 7,2010

What is the balanced equation for the combustion of hexane?
2c6h14 + 15o2 -> 12co2 + 14h2o Stupid site again!! All letters are capitals.
Is C6H14 an organic or inorganic compound?
C6H14 is an organic compound. It is a type of hydrocarbon known as a hexane, which consists of carbon and hydrogen atoms bonded together in a specific structure. Organic compounds are typically derived from living organisms and contain carbon-hydrogen bonds.
Would you expect hexane to be soluble in water?
The density of cyclohexane is lower than that of water (0.779 g/mL vs. 1.0 g/mL respectively), so it will float on top of water.
What is the denisty of hexane?
The Density of Hexane is 0.6548 g/ml.
Is hydrogen sulfide soluble?
Yes, hydrogen sulfide (H2S) has some solubility in water depending on temperature.The solubility of H2s in water is approximately:0.4 g H2S /100 mL solution (20 °C)0.25 g H2S/100 mL solution (40 °C)More detailed data is provided in the links below.
How many moles of hydrogen sulfide are contained in a 64.6-g sample of this gas?
To find the number of moles of hydrogen sulfide, divide the given mass by the molar mass of hydrogen sulfide. The molar mass of hydrogen sulfide is approximately 34.08 g/mol. Thus, 64.6 g / 34.08 g/mol = 1.9 moles of hydrogen sulfide in the sample.
What mass of carbon dioxide can be produced from 25.0g of C6H14 and excess oxygen?
The gram molecular mass of hexane is 86.18. Therefore, 25.0 g of hexane constitute 25.0/86.18 or 0.290 moles. Each mole of hexane contains six carbon atoms and therefore will produce six molecules of carbon dioxide by burning in an excess of oxygen. 6 X 0.290 = 1.74 moles of carbon dioxide. The gram molecular mass of carbon dioxide is 44.00. Therefore, the mass of carbon dioxide produced will be 1.74 X 44.00 or 76.6 grams of carbon dioxide, to the justified number of significant digits.
Is ice more dense than hexane?
No, ice is not more dense than hexane. Ice has a density of about 0.92 g/cm³, while hexane has a density of approximately 0.66 g/cm³. This lower density of hexane means that ice will float on hexane when the two are combined.
What is the mole fraction of H2S in a mixture of gases made up of 7.0 g of H2S 10.0 g of CH4 and 12.0 g of O?
First calculate the moles of each gas using their molar masses (H2S = 34 g/mol, CH4 = 16 g/mol, O2 = 32 g/mol). Then find the total moles in the mixture. Lastly, divide the moles of H2S by the total moles to get the mole fraction of H2S in the mixture.
