What is the formula mass for ethyl alcohol C2H5OH?
46.07 g/mol
Ethanol/Molar mass
What is the mass of 2 moles of ethanol?
1, the molecular mass of ethanol is 46.069 amu. Because 1 mol of ethanol contains 2 mol of carbon atoms (2 × 12.011 g), 6 mol of hydrogen atoms (6 × 1.0079 g), and 1 mol of oxygen atoms (1 × 15.9994 g), its molar mass is 46.069 g/mol.
How many moles of ethyl alcohol does C2H5OH have?
∴ in 65 ml of ethyl alcohol solution, 1.5/1000 × 65 = 0.0975 mol of ethyl alcohol. therefore the number of moles of ethyl alcohol is 0.0975. also read similar questions : 92 g of ethyl alcohol (C2H5OH), 62 g of ethylene glycol (C2H602) and 96 g of methyl alcohol (CH3OH) are present in a sol…
How many moles are there in ethyl alcohol?
In this case, ethanol’s molecular mass is 46 g/mol. This means that in 1 mol of ethanol, there are 46 g, thus the term molecular mass and molar mass are often used interchangeably. The same is true of a mole. A mole of anything is 6.022 x 1023 of that item.
What is the formula mass of copper II chloride?
134.45 g/mol
Copper(II) chloride/Molar mass
What is the mass of 0.2 moles of ethanol C2H5OH?
Answer is 9.2 g. hence option “d” i s correct.
What is the mass of 0.20 mole of C2H5OH?
Answer is 9.2 g.
What is the chemical formula for ethyl alcohol?
C2H5OH
Ethanol/Formula
The molecular formula of ethanol is C2H6O, indicating that ethanol contains two carbons and an oxygen. However, the structural formula of ethanol, C2H5OH, provides a little more detail, and indicates that there is an hydroxyl group (-OH) at the end of the 2-carbon chain (Figure 1.1).
What is the formula for Copper II sulfate?
CuSO4
Copper(II) sulfate/Formula
Copper(II) sulfate, also known as copper sulphate, are the inorganic compounds with the chemical formula CuSO4(H2O)x, where x can range from 0 to 5. The pentahydrate (x = 5) is the most common form.
