Answer: 0.256 g
Explanation:
The deposition of Ga from Ga(III) solution
According to mole concept:
1 mole of an atom contains number of particles.
We know that:
Charge on 1 electron =
Charge on 1 mole of electrons =
where,
I = current passed = 0.590 A
q = total charge = ?
t = time required = 30.0 min = 1800 s (1min=60s)
Putting values in above equation, we get:
will deposit = 70 g of Gallium
will deposit =
of Gallium
Thus 0.256 g of Ga(s) that can be deposited from a Ga(III) solution using a current of 0.590 A that flows for 30.0 min.
The volume of the liquid = 8.7 ml
<h3>Further explanation</h3>Graduated cylinder is a laboratory tool used to measure the volume of liquid
Also called a measuring cylinder
Each line (marked line) on this cylinder shows a scale that shows the total volume of water.
The reading is based on a curve of the fluid formed called the meniscus. Read the measurement of the amount of fluid at the bottom of the meniscus (the position of our eyes is parallel to the level of the meniscus and the cylinder is located in a flat (not tilted) place
If we look at the picture (attached), the meniscus is located between the scale / line 8.6 and 8.8(interval 0.2 ml), so the volume of the liquid shows the number 8.7 ml
