No of moles = given mass ÷ molecular mass
n = 55.98 ÷ (12+19×2+35.5×2)
First, find moles of oxygen gas: (3.01 x10^23 molec.)/(6.02 x10^23) =0.5mol O2
Second, multiply moles by the standard molar volume of a gas at STP:(0.5mol)(22.4L) = 11.2L O2
Answer:
Elements combine to form chemical compounds that are often divided into two categories
When two or more atoms chemically bond with each other, the resultant chemical structure is a molecule.
Chloroacetic acid is stronger than acetic acid because of the electron-withdrawing effect of chlorine. This effect is caused by the electronegativity.
