Question

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

Answer 1

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

Answer 2

Answer:

9.99 ml water will be delivered from pipet

Explanation:

When Water is being delivered by the pipet the temperature is 19 degree Celsius. Also know that dependence of density is on temperature although this temperature dependence is inverse in nature that is when temperature increases density decreases and vice versa.

Now we also know the density of water at 20 ° Is $0.99 gml-1$.

At this temperature 9.98 gram will occupy a volume= $0.98/0.998= 9.997ml$
