# How many moles of the indicated solute does each of the following solutions contain? a. 1.5 L of 3.0 M HSO4 solution b. 35 mL of 5.4 M NaCl solution c. 5.2 L of 18 M H2SO4solution d. 0.050 L of 1 . 1 × 1 0 − 3 NaF solution

Interpretation Introduction

(a)

Interpretation:

The moles of the indicated solute in the given solution are to be calculated.

Concept Introduction:

The atomic mass of an element is defined as the sum of number of protons and number of neutrons. Molar mass of an element is determined from atomic mass of an element.

The number of moles is calculated by the formula,

Moles=MassgMolarmass

The molarity is calculated by the formula,

Molarity=NumberofmolesofsoluteVolumeofsolutionL.

Explanation

The volume and molarity of H2SO4 solution is given to be 1.5L and 3.0M respectively.

The number of moles of a solute is calculated by the formula,

Numberofmolesofsolute=Volumeofsolution×Molarity

Substitute the values of volume and molarity of H2SO4 solution in the above expression
