In biological applications it is often preferable to measure solution concentrations in molality rather than molarity especially if comparing solutions of two different substances This is because?
if one scientist reports concentrations measured in molality, another scientist elsewhere can exactly replicate the work. This is not possible with molarity. I chose the above answer on my quiz and it was actually incorrect. The correct answer should be - two solutions of the same molality have equivalent ratios of solute to water, but two solutions of the same molarity may not have equivalent ratios.
When does molarity and molality become equal?
In dilute solutions... ie closer a solution is to pure water the closer molality and molarity come to equalling each other. This is because the molality uses mass and molarity uses volume, the ratio of these two (mass and volume) is density, and water has the density of 1 therefore the mass and volume are equal to each other. THEREFORE calculating the molarity of water is the same as calculating the molality of water.
Why concentrated Hcl is 12N?
For solutions where there is only one hydrogen atom per molecule (HCl) N is the same as molarity (M). It differs only when there is more than one hydrogen atom per molecule.
Is normality and molarity for silver nitrate same?
Yes, it is true.
How do you make HCl 5 normal?
Normality is the same as Molarity assuming there is only 1 exchangeable proton. Hence, 5 Normal = 5 Molar, which is 5 mol of HCl per Liter of solvent (water)

What is the molarity of a solution that contains 0.55 moles of a substance dissolved in half a liter of solution?
Molarity means moles per litre. You have to keep that same ratio. i.e. .55moles in 0.5 litres is the same as 1.1 moles in a litre. Therefore the molarity is 1.1 molar.
What is an equation that have the same solutions?
Simultaneous equations have the same solutions.
What is equations that have the same solutions?
Simultaneous equations have the same solutions.
What is the difference between morality of a substance and twice the morality of the same substance?
I believe you mean molarity. Molarity is a unit of concentration. So if the number is twice as big...
Would molarity increase if room temperature increased?
would molarity increase, decrease, or stay the same if the room temperature increased by 5 degrees centigrade
What is the molarity of the solution containing 5.0 moles of KCl in 2.0 L of solution?
Molarity is moles per litre. So you have to convert volume to a litre. i.e. 0.5x2 is a litre. so you have to do the same to moles. 5x2 is 10 moles. as this is per litre, it is a 10 molar solution.
Solutions that have the same osmotic pressure are called .?
Solutions having the same osmotic pressures are called isotonic solutions
