What is the SI unit of momentum?
The unit of momentum is the product of the units of mass and velocity.
In SI units, if the mass is in kilograms and the velocity is in meters per second then the momentum is in kilogram meters per second (kg⋅m/s)..
What is difference between molality and molarity?
An important distinction between molality and molarity is the difference between a solution and a solvent. Molarity is the ratio of the moles of a solute to the total liters of a solution. … Molality, on the other hand, is the ratio of the moles of a solute to the kilograms of a solvent.
What is TITR?
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete.
How do you make 1m NaOH?
Popular Answers (1) of moles of solute / 1 liter . * one moles of sodium hydroxide = 40 gm of sodium hydroxide. so we can said ; if want prepare 1 molar NaOH solution then we need 40 gm NaOH dissolve in one liter of water so it became one 1 molar NaOH solution.
What is normality formula?
Normality is defined as the number of equivalents of solute dissolved per liter of solution (equivalents/L = N) (Equations 1, 3, and 4). … EW is the equivalent weight in g/equivalent. It is calculated by dividing the molecular weight of solute by the number of equivalents per mole of solute (Equation 2).
What is meant by molarity?
noun Chemistry. the number of moles of solute per liter of solution.
Is molarity a unit?
Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution. Molarity can be used to calculate the volume of solvent or the amount of solute.
What is SI unit of force?
The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.
What is Molality example?
Molality is defined as the number of moles of solute present in 1000 gm of the solvent. … Example: Calculate the molality of a solution prepared from 29.22 grams of NaCl in 2.00 kg of water.
What is unit of concentration?
In chemistry, concentration of a solution is often measured in molarity (M), which is the number of moles of solute per liter of solution. This molar concentration (ci) is calculated by dividing the moles of solute (ni ) by the total volume (V) of the: ci=niV. The SI unit for molar concentration is mol/m3.
What is the SI unit of molarity and molality?
The SI unit of concentration is mol ˣ m-3 with molarity (M) and molality (m) being recommended for discontinuance by SI. It is expected that molal be replaced by mol ˣ kg-1 and the rarely used term molality be discontinued as it may be confused with the commonly used term molarity .
How do you make 1 N HCL?
1N HCL – add 36.46 gm of HCL in 1 litre of water (Molar mass of HCL = 36.46 g/mole)36.46 g of HCL is equivalent to 30.67 ml of HCL ( Volume = Mass/Density = 36.46/1.19 = 30.67)Density of HCL is = 1.19 g/ml.Percent Concentration of Most Conc HCL is = 37.5 %More items…

What is the SI unit of normality?
Normality is a unit of concentration of a chemical solution expressed as gram equivalent weight of solute per liter of solution. A defined equivalence factor must be used to express concentration. Common units of normality include N, eq/L, or meq/L.
What is mole in chemistry?
Mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
