Explanation:
The reaction between acetic acid and NaOH will be:
Thus one mole of acetic acid will react with one mole of NaOH.
The moles of NaOH used = molarity X volume = 0.1 X 30.10 mL = 3.010 mmol
The moles of acetic acid reacted = 3.010 mmol
The moles of acetic acid will be used to calculate the mass of acetic acid used
Mass of acetic acid used = moles X molar mass = 3.010mmol X 60
mass of acetic acid used = 180.6 mg = 0.1806 g
The mass of vinegar used = 5.54 g
The percentage of acetic acid in vinegar will be =%

Answer: Thus the mass, in grams, of 27 moles of smooth muscle myosin is 12960000 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass, occupies 22.4 L at STP contains avogadro's number of particles.
Molecular mass of protein = 480,000 g/mol
Thus 1 mole of protein weighs = 480,000 g
So 27 moles of protein weighs =
Thus the mass, in grams, of 27 moles of smooth muscle myosin is 12960000 grams
