The -COOH is bonded to a long chain of hydrocarbons in a fatty acid.
A hydrocarbon chain is comprised of both carbon (C) and hydrogen (H) atoms. The 'acid' part is made up of the -COOH portion, whereas the 'fatty' part is made up of the long hydrocarbon chain that it is attached to.
Answer:
119.28g
Explanation:
Data obtained from the question include:
Number of mole of Si = 4.26 mol
Molar Mass of Si = 28g/mol
Mass of Si =?
Number of mole = Mass /Molar Mass
Mass = number of mole x molar Mass
Mass of Si = 4.26 x 28
Mass of Si = 119.28g
Wavelength = (planck’s constant) (speed of light) / Energy
6.2 (Energy) = (6.63 •10^-34) (3•10^8)
1.989•10^-25 / 6.2 =
3.2081 • 10^-26 is the answer
Answer:
Explanation:
159 mL of .135 M benzoic acid will contain
.159 x .135 = .021465 moles of benzoic acid.
Molecular weight of benzoic acid = 122 gm
grams of .021465 moles = 122 x .021465 = 2.6 grams .
So 2.6 grams of benzoic acid will be required .
