Stu and noke are working with a red food coloring, red #40. the stock solution has a concentration of 0.0880 m dye. noke want to makes a concentration of 0.0088 m, exactly one tenth of the original red dye solution strength. what volume of the original 0.0880 m solution should she measure into a 100.0 volumetric flask, to be diluted with water up to the line of the flask? (3 significant digits, unit ml)

2)stu dilutes the stock 0.0880 m red dye solution (same as the previous question by measuring 25.00 ml with a pipet into a 100.0 ml volumetric flask and then adding water up to the line on the flask. calculate the new concentration of his diluted solution. (round to 3 significant digits, unit m)

1. Volume of the original 0.0880 M solution should Nok measure into 100 mL volumetric flask is 10.0 mL.

2. The new concentration of diluted solution is 0.0352 M.

Explanation:

1) Concentration of solution given =

Volume of solution red dye solution of 0.0880 M needed =

Required concentration of red dye solution =

Volume of solution red dye solution required=

Volume of the original 0.0880 M solution should Nok measure into 100 mL volumetric flask is 10.0 mL.

2) Concentration of red dye solution given =

Volume of solution red dye solution of 0.0880 M added into volumetric flask=

Required concentration of red dye solution =

Volume of solution red dye solution required=

The new concentration of diluted solution is 0.0352 M.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

they are both synthetic elements
