Question

2Student Name n Hundal Date 2/22/18 Data and calculations for maldng solutions. 1) Complete the table using numerical values from the Dota page. Pay attention to significant digits Mass of Nad2.3985 8 Concentration of solution (molarity)04107 M 100 mL Concentration of solution (molarity) 0.1027 M First solution: Volume of volumetric flask used Second solution: Volume of first solution (pipet) Volume of volumetric flask used Third solution: Volume of first solution (pipet) Volume of volumetric flask used Concentration of solution (molarity) Doc Inmaking and Stu Dent make the two solutions described below. Help them do the calculations with M·v, Doc makes the first solution by pipeting 20 mL of6.0 MHCl(aa) into a 250 mL volumetric flask. Hefills the rest of theflask with DI water to the line. The concentration of the first solution is … Stu makes the second solution by pipeting 5 mL of Doc's first solution into a 100 ml volumetric flask. He fills the rest of the flask with DI water to the line. The concentration of the second solution is... 2) ,v, Data and calculations for glassware accuracy and costs 8) Complete the tables using numerical values from the second Data poge. Payattention to significant digits Uncertainty (tml) Cost (S) Size 2 mL 5 mL 10 mL Representative volumetric pipets

Explanation / Answer

M1V1=M2V2

where M1=6.0

V1=20mL

V2=250

putting the values we get M2=0.023M

first solution is 0.023M

for second solution

M1V1=M2V2

where M1=0.023

V1=5mL

V2=100mL

putting the values we get M2=0.00115M

second solution is 0.00115M
