Molarity is defined as the number of moles of solute in 1 L of the solution.
Since the mass of the solute has been given we have to obtain the number of moles of solute
Number of moles = mass / molar mass
So we need to convert the mass to number of moles by dividing the mass by its molar mass.
The volume of the solution needs to be given in L but it has been measured in ml. Therefore volume in mL should be converted to L.
The molarity is found by dividing the number of moles by volume of solution in L

Jose’s lab instructor gives him a solution of sodium phosphate that is buffered to a pH of 4. Because of an error that he made w
RoseWind [281]
His measurements are precise since his pH values are close to each other in a way that it was repeated in all measurements. On the contrary to accuracy, it is the closeness to the actual pH value he should have achieved. Therefore, Jose's results are precise but not accurate since his value is not close to the actual value of pH 4.

adell [148]

Answer:

The correct answer is vertebrate enzyme hydrolyze alpha-1,4 glycosidic linkage but not glucose in the beta configuration.

Explanation:

The amylase that is present inside human body is called salivary alpha amylase,an enzyme that digest the alpha-1,4-glycosidic linkages of starch but does not act on those glycosidic linkages which are present in beta configuration.

       Cellulose contain beta-1,4-glycosidic linkages.That"s why it is not digested by the alpha amylase enzyme present inside the human body basically present in the saliva.
