The formula for ethyl alcohol is C2H5OH the mass of 2 moles of ethyl alcohol would be grams?
92
How many grams does 5.60 x 1022 molecules of SiO2?
To find the mass, we divide by Avogadro's number to find the amount of moles. We then multiply the moles by the molar mass of the compound which is 60.08 grams. Doing all of this, we get a mass in grams of 5.59 grams.
What weighs 75 grams?
Moles are very light and an Eastern Mole weighs only 75 grams. The Eastern Mole is also known as the Scalopus aquaticus.
In the reaction 2 RbNO3-- 2 RbN plus 3O2 how many moles of O2 are produced when 5 mol of RbNO3 decompose?
5 moles RbNO3 (3 moles O2/2 moles RbNO3) = 7.5 moles oxygen gas produced
What can the coefficients in a balanced chemical equation always express the ratio of?

The formula for ethyl alcohol is C2H5OH the mass of 2 moles of ethyl alcohol would be grams?
92
The formula for ethyl alcohol is C2H5OH. The mass of 2 moles of ethyl alcohol would be how many grams?
The molar mass of ethyl alcohol (C2H5OH) is 46.07 g/mol. Therefore, the mass of 2 moles of ethyl alcohol would be 92.14 grams (46.07 g/mol x 2 mol).
How many grams are there in 1.36 mol of ethyl alcohol?
To convert moles to grams, you need to use the molar mass of ethyl alcohol. The molar mass of ethyl alcohol (C2H5OH) is approximately 46.07 g/mol. Therefore, 1.36 mol of ethyl alcohol would be 1.36 mol x 46.07 g/mol = 62.59 grams.
How many grams of solute are used in 270.0mL of 0.650M ethyl alcohol?
To find the grams of solute, first calculate the moles of ethyl alcohol using the given concentration (0.650 mol/L) and volume (270.0 mL). Then, use the molar mass of ethyl alcohol (46.07 g/mol) to convert moles to grams. The calculation would be: 0.650 mol/L * 0.270 L * 46.07 g/mol = 7.05 grams of ethyl alcohol.
How many moles are in 92g of ethanol?
To find the number of moles in 92g of ethanol, we first need to know the molar mass of ethanol, which is approximately 46g/mol. Then, we divide the given mass by the molar mass to get the number of moles. So, 92g of ethanol is equal to 2 moles.
Combustion of 2.22 mg of ethyl butyrate produces 5.06 mg of CO2 and 2.06 mg of H20 what is the empirical formula?
To find the empirical formula, you need to determine the moles of each element present in the given compounds. Convert the given masses of CO2 and H2O to moles, then calculate the moles of C, H, and O in ethyl butyrate. Finally, find the simplest whole-number ratio of these moles to determine the empirical formula, which in this case is C5H10O2.
How many moles of ethyl alcohol C2H6O are in a 32.0 g sample Express your answer using three significant figures.?
32 g ethanol is equivalent to 0,695 moles.
How to find the empirical formula from percentages?
To find the empirical formula from percentages, convert the percentages to grams, then divide the grams by the element's molar mass to find the moles. Finally, divide the moles by the smallest number of moles to get the ratio of elements in the compound, which represents the empirical formula.
How many grams of NaOH(MW40.0) are there in 400.0 ml of a 0.175 M NaOH solution?
To calculate the grams of NaOH in the solution, you first need to find the moles of NaOH present in 400.0 ml of the solution. The moles of NaOH can be calculated using the formula: moles = molarity x volume (in liters). Once you have the moles of NaOH, you can then calculate the grams using the formula: grams = moles x molecular weight.
Formula for moles?
number of moles = mass of the material/molar mass
How do you calculate the empirical formula using percentages?
To calculate the empirical formula using percentages, first convert the percentages to grams. Then divide the grams by the element's molar mass to find the moles. Finally, divide the moles by the smallest number of moles to get the ratio of elements in the compound, which represents the empirical formula.
He formula for potassium dichromate is KËÃCrËÃOËÈ How many grams of oxygen will be in 2 moles of potassium dichromate?
In 2 moles of potassium dichromate, there are 16 moles of oxygen atoms (from the two oxygen atoms in each formula unit). The molar mass of oxygen is 16 g/mol, so in 2 moles of potassium dichromate, there are 32 grams of oxygen.
