Question

How many millilitres of a stock solution of 6 m hno3

Answer 1

Answer:

I used the equation M1V1=M2V2

6M*V1 = 0.190L*0.490 M

lead me to this V1=0.190L*0.490M/6.00 M

=0.0931 L per M/6.00M

=0.0155166L

0.0155166L/1000mL= 0.155166L

Answer 2

The solution obtained after dilution is less concentrated (has less solute's amount) as compared to the stock solution which is more concentrated. This decrease in concentration is achieved by adding excess solvent.I'm assuming that 6.0m is a typo and you meant 6.0M.(There is a difference).mL1 x M1 = mL2 = M2mL1 x 6.0M = 110 mL x 0.500m.
