The mass of NaCl in a given solutions is to be calculated. Concept Introduction: The same solute and solvent can form a number of combinations by varying their amounts. These combinations can be differentiated in terms of concentration of solution. The amount of a solute present in a given amount of a solvent is defined as its concentration. Mass percent is defined as the mass of a solute present in 100 g of a solution. Density is the ratio of the mass of a substance to its volume. A mole is a unit of amount of a substance. It relates the number of particles to molar mass. Density of a solution as presented as: Density = Mass of solution Volume of solution As 1 L is equal to 1000 mL, hence the conversion factor will be as: 1000 mL 1 L Mass percent of compound = Mass of compound Mass of solution

Interpretation Introduction

Interpretation:

The mass of NaCl in a given solutions is to be calculated.

Concept Introduction:

The same solute and solvent can form a number of combinations by varying their amounts. These combinations can be differentiated in terms of concentration of solution. The amount of a solute present in a given amount of a solvent is defined as its concentration.

Mass percent is defined as the mass of a solute present in 100 g of a solution.

Density is the ratio of the mass of a substance to its volume.

A mole is a unit of amount of a substance. It relates the number of particles to molar mass.

Density of a solution as presented as:

Density=Mass of solutionVolume of solution

As 1 L is equal to 1000 mL, hence the conversion factor will be as:

1000 mL1 L

For the compound: C8H17NO2 Use the following information to come up with a plausible structure: 8 This compound has "carboxylic acid amide" and ether functional groups. The peaks at 1.2ppm are two signals that are overlapping one another. One of the two signals is a doublet that represents 6 hydrogens; the other signal is a quartet that represents 3 hydrogens.
