A piper delivers 9.98 g of water at 19 degrees Celsius. What does the pipet deliver
leva [86]

Answer:

the volume = 9.99 ml

Explanation:

in your Q we need to calculate the volume does the pipet deliver so , we are going to use this formula:

the volume = mass / density

here we need to know the density of water at a certain temperature 19 degrees Celsius ,so I used an external source   to get the density of water at 19 degrees Celsius because it is changing with different temperatures

where mass here = 9.98 g

and  the density of water at  temperature 19 degrees Celsius=  0.998405mL

-1

by substitution :

the volume = 9.98 g / 0.998405mL

-1

                   ≅ 9.996 ml = 10 ml
