molarity =Number of moles of compound*1000/(mass of solvent)
Number of moles of NaCl=Given mass/molar mass
Given mass of NaCl=14.3 g
molar mass of NaCl=58.44g
Number of moles of NaCl= 14.3/58.44
=0.244
Mass of solvent (Water)=42.2 g
Molarity=0.244*1000/(42.2)
= 5.80m
Explanation:
IR (infrared) spectroscopy theory is based on the concept that the molecules tend to absorb some specific amount of the frequencies of light which are characteristic of corresponding structure of molecules. These energies are reliant on shape of molecular surfaces, associated vibration coupling, and mass corresponding to atoms.
It is used to detect the type of the functional group present in the organic compound.
An SDOF system is one whose motion is governed by a single, second-order differential equation. Only two variables, position and velocity are needed to describe the trajectory of the system. Many structures can be idealized as single degree-of-freedom systems.
The LDAP Data Interchange Format is a standard plain text data interchange format for representing LDAP directory content and update requests. LDIF conveys directory content as a set of records, one record for each object.
Answer:
a. molarity
e. molality
h. density
b. weight percent
g. volume percent
Explanation:
Molarity is defined as the number of moles of substance dissolved in per liter of solution (moles/Liter). It is also called molar concentration of the solution.
Molality is defined as the number of moles of substance dissolved in one kg or kilogram of solvent and its SI unit is mol/kg.
Density is defined as the mass divided by its volume.
density =mass/volume
Weight percent is defined as the division of mass of a solute to the mass of the total solution, multiplied by 100. To calculate the weight percent or mass percent, both mass of a solute and the mass of a solution is required to express the concentration of a solution.
Volume percent is defined as the ratio of the volume of the solute to the volume of the total solution multiplied by 100.
