Explanation:
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
