Answer:
162 grams
Explanation:
To find the mass from molar mass and moles, you simply multiply.
You get (18.0g)x(9.00 moles)
Answer:
V = 0.0007678398L
Explanation:
Given parameters:
Number of moles of gas = 3.43moles
Temperature = 273k
pressure = 100kPa = 100000Pa
Unknown:
Volume of gas = ?
Solution
The gas is at standard temperature and pressure, this implies we can use the ideal gas equation to solve for the unknown.
Mathematically, the law is expressed as:
PV = nRT
The unknown here is the Volume, V. We know the other parameters.
P = pressure on the gas
n = number of moles
R = gas constant=0.082
T = temperature
now, we have to make V the subject of the expression:
V = 
V = 
V = 0.0007678398L
Alcohols always contain the Hydroxyl functional group (-O H) - (or just hydroxyl group), which is an oxygen atom bound by a covalent (with shared electron pairs) bound to a hydrogen atom.
