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
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 .
At this temperature 9.98 gram will occupy a volume=
