How many ml of a 0.300 m agno3 solution will it take to make 500 ml of a 0.100 m agno3 solution?

We need 166, 7 mL of AgNO3 [0.300M] to prepare 500mL of AgNO3[ 0.100M]

Explanation:

When calculating the amount of volumen from an initial solution in order to prepare other one. we always use this formula for dilutions.

C1V1=C2V2

Inicial conditions that will be represented by  number 1

C1= 0.300M AgNO3

V1=  ?

Final conditions that will be represented by  number 2

C2= 0.100M AgNO3

V2=  500mL

V1= C2. V2 / C1

V1= 0.100M. 500mL /0.300M

V1= 166.7 mL

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
