The friction aids in grasping and walking. The friction ridge skin also contains numerous sweat glands, and the pore openings are located along the tops of the ridges. The friction ridge skin does not contain sebaceous (oil) glands or hair follicles.
Answer: M = 22/ (i x28.948)
Explanation:
Pi = osmotic pressure = 22atm
T = Temperature = 353K
M = Molarity = ?
R = gas constant = 0.082atm.L/mol/K
i = van’t Hoff factor
Pi = iMRT
M= Pi /(iRT) = 22 / ( i x 0.082 x 353)
M = 22/ (i x28.948)
Answer:-
0.231 moles
Explanation:-
From the question we are told that
Volume of HCl solution = 0.70 L
Strength of HCl solution = 0.33 M
Here M stands for molarity. Molarity is the number of moles of the substance present per Litre of solution. So in place of M we can write moles / L
Number of moles of HCl solution = Volume of HCl solution x Strength of HCl solution
= 0.70 L x 0.33 moles / L
= 0.231 moles.
0.231 moles of HCl are present in 0.70 L of a 0.33 M HCl solution
