What is the percent by mass of oxygen in propanol?
The molar mass of propanol (C3H8O) is approximately 60.08 g/mol. Oxygen has a molar mass of 16 g/mol. To find the percent by mass of oxygen in propanol, divide the molar mass of oxygen by the molar mass of propanol and multiply by 100. This gives a percentage of around 26.6%.
How many moles of propanol C3H8O are there in 42.1g of propanol?
To find the number of moles in 42.1g of propanol (C3H8O), divide the given mass by the molar mass of propanol. The molar mass of propanol is 60.1 g/mol (3 carbons with a molar mass of 12.01 g/mol each, 8 hydrogens with a molar mass of 1.01 g/mol each, and 1 oxygen with a molar mass of 16.00 g/mol). So, 42.1g / 60.1 g/mol = 0.70 moles of propanol.
What is the percent composition of propanol?
Propanol, also known as 1-propanol, has a chemical formula of C3H7OH. To find its percent composition, calculate the molar mass of propanol. The molar mass is approximately 60.1 g/mol. To determine the percent composition, divide the molar mass of each element by the molar mass of the compound and multiply by 100. Oxygen contributes around 15.0%, carbon about 60.0%, and hydrogen approximately 25.0% to the overall mass of propanol.
How many grams of water and propene can be formed from the reaction of 6.0 grams of 2-propanol?
To determine the amount of water and propene that can be formed, we first need to write out the balanced chemical equation for the reaction of 2-propanol (C3H8O) to form water (H2O) and propene (C3H6): C3H8O -> C3H6 + H2O Next, calculate the molar mass of 2-propanol (60.1 g/mol) and the molar masses of water (18.0 g/mol) and propene (42.1 g/mol). Then, use stoichiometry to convert the mass of 2-propanol to moles, and from there determine the amount of water and propene that can be formed.
How can one determine the molar mass from molality?
To determine the molar mass from molality, you can use the formula: Molar mass (molality x molar mass of solvent) / molality of solute. This equation helps you calculate the molar mass of a substance based on its molality in a solution.

How many grams of carbon dioxide are produced when 23.5 g of propanol react with excess oxygen in a combustion reaction?
First, calculate the moles of propanol (C3H7OH) using its molar mass. Then, use the balanced chemical equation for the combustion reaction of propanol to find the moles of carbon dioxide produced. Finally, convert moles of carbon dioxide to grams using its molar mass to find the mass produced.
How many grams of water and propene can be formed from the reaction of 6.0 grams of 2-propanol?
To determine the amount of water and propene that can be formed, we first need to write out the balanced chemical equation for the reaction of 2-propanol (C3H8O) to form water (H2O) and propene (C3H6): C3H8O -> C3H6 + H2O Next, calculate the molar mass of 2-propanol (60.1 g/mol) and the molar masses of water (18.0 g/mol) and propene (42.1 g/mol). Then, use stoichiometry to convert the mass of 2-propanol to moles, and from there determine the amount of water and propene that can be formed.
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
What is the molar enthalpy of formation of propanol?
The molar enthalpy of formation of propanol (C3H7OH) is approximately -455 kJ/mol. This value represents the heat released when one mole of propanol is formed from its elements in their standard states at 25°C and 1 atm.
