Molality is defined as the number of moles of solute present in 1L of solution.
Molality (M) = No of moles of solute / 1 L of solution
Litre of solution = No of moles of solute / Molality
Molality = 0.220M
No of moles= 0.0170 mol
Volume in L = 0.0170/0.220
= 0.0772 L
Volume in mL = 77.27 mL
What is mole?
- A mole is a very important unit of measurement used by chemists.
- moles of something means there are 602,214,076,000,000,000,000,000,000,000,000 number of something.
- Chemists need to measure very small things such as atoms, molecules and other particles in moles.
- 602,214,076,000,000,000,000,000 is called Avogadro's number, abbreviated as 6.02 x
Therefore, Volume in ml of 0.220 m hbr solution is required to produce 0.0170 moles is 77.27 mL.

Answer: transfer of heat by the actual movement of warmed matter
Explanation: convection is the process of heat transfer through fluids. When molecules absorbs heat they become excited and less dense causing it to rise.

Answer:
<h3>"Pearson correlation coefficient"</h3>
The correlation coefficient, denoted by r, tells us how closely data in a scatterplot fall along a straight line. The closer that the absolute value of r is to one, the better that the data are described by a linear equation. If r =1 or r = -1 then the data set is perfectly aligned.
