How do you calculate the density of an ethanol-water mixture?
To calculate the density of an ethanol-water mixture, you would use the formula: Density (mass of ethanol mass of water) / (volume of ethanol volume of water) You would need to know the masses and volumes of both ethanol and water in the mixture. Then, you can plug these values into the formula to find the density of the mixture.
What is the mole fraction of water in a water ethanol solution that is 57 percent water by mass?
To calculate the mole fraction of water in the solution, we first need to determine the moles of water and ethanol present. Given that the solution is 57% water by mass, we can assume the remaining 43% is ethanol. From there, we can convert the mass percentages to moles using the molar masses of water and ethanol, and finally, calculate the mole fraction of water by dividing the moles of water by the total moles of the solution.
What is the percent carbon in CH3CH2OH?
To calculate the percent carbon in ethanol (CH3CH2OH), you can sum the atomic masses of the carbon atoms and divide by the molecular weight of the compound. In ethanol, there are two carbon atoms. The percent carbon can be calculated as (2 * 12.01 g/mol / 46.08 g/mol) * 100% = 52.08% carbon.
What is added to ethene to produce ethanol?
If starting with ethane C2H6 the hydrogens must be reduced to form C2H4 (ethylene) creating a double bond between the carbons (H2C=CH2) This compound (ethylene) is exposed to concentrated sulfuric acid (breaking the bond) and forming C2H3SO4H then water to substitute an OH group on one carbon to form H3CH2OH (ethanol) Alternately the ethylene may be catalyzed by phosphoric acid on a substrate to hydrolize directly to form ethanol.
In the Mixtures lab you waited to see if the liquid would form lumpy or fluffy masses which would indicate it was a?
heterogeneous mixture. Lumpy masses would suggest that the substances did not fully mix together, while fluffy masses would indicate a more homogeneous distribution of particles in the liquid.

Then, you can plug these values into the formula to find the density of the mixture.
What is the theoretical yield of ethanol?
This question cannot be answered as written. The chemical equation is needed, as well as the masses of the reactants.
A mixture is prepared using equal masses of the two volatile liquids benzene and ethanol What is the mole fraction of benzene in this mixture?
0.371
Do air masses ever mix together?
Yes, air masses can mix together when they come into contact with each other along fronts or boundaries. When different air masses with contrasting temperature, humidity, and density characteristics interact, they can blend and influence the weather patterns in the region where they mix.
When two air masses meet at a front air from both air masses typically?
Mixes together, causing precipitation
What would have the greatest gravitational attraction between the two masses?
The gravitational attraction between two masses depends on their masses and the distance between them. If the masses are large and close together, they would have the greatest gravitational attraction.
WHAT is the force that pulls masses together?
The force that pulls masses together is gravity. It is a fundamental force of nature that acts between all objects with mass, causing them to be attracted to each other.
What landform are formed by the crashing of tow land masses?
Two land masses crunching together will form mountains E.g. Himalayas
What cause moving air?
The temperature and density of the air masses. the air masses moves when hot air and cold air gets together
What is the molar mass of C2H5OH?
A molecule of ethanol has 2 carbon atoms, 6 hydrogen atoms and 1 oxygen atom. Their atomic masses are 12, 1 and 16 in order. By adding of the masses, the molecular mass of ethanol is 12x2+1x6+16=46u.
Is there Catholic Mass in English at the Vatican?
yes, there is, together with Masses in different languages.
