a)
D = 0.79 g/cm³ m = 85.1 g
D = m / V
0.79 = 85.1 / V
V = 85.1 / 0.79 => 107.72 cm³
____________________________________________
b) D = m / V
0.79 = m / 125
m = 0.79 x 125 => 98.75 g

hope this helps!
Hydroponics is more than just another way to grow plants–the technology has the potential to change how we engage with food cultivation as a whole! For the first time since humans started tilling the land, modern hydroponics technology frees us from the soil beneath our feet, allowing us to bring food production indoors where we can layer in additional climate and lighting controls. The result is an ability to grow food anytime, anywhere in the world.
The liquid that is been dispensed during titration as regards this question is Titrant.
- Titration can be regarded as common laboratory method that is been carried out during quantitative chemical analysis.
- This analysis helps to know the concentration of an identified analyte.
- Burette can be regarded as laboratory apparatus.
It is used in the in measurements of variable amounts of liquid ,this apparatus helps in dispensation of liquid, especially when performing titration.
- The specifications is been done base on their volume, or resolution.
- The liquid that comes out of this apparatus is regarded as Titrant, and this is gotten during titration process, which is usually carried out during volumetric analysis.
Therefore, burrete is used in volumetric analysis.
