2(5) + 2 (z) = 10{3}
10 + 2z= 30
2z=20
z=10
To solve this problem we will use Henry's law. This law states that at a constant temperature, the amount of gas dissolved in a liquid is directly proportional to the partial pressure exerted by that gas on the liquid. Mathematically it is formulated as follows:

Where,
= Henry's constant for C02 at 25°C is equal to 
C = Gas concentration is 0.19M
Replacing we have,


Therefore the pressure of carbon dioxide is 5.277 atm
Answer: Resistance =
, Current = 1.56 A, Voltage =4.99 V
The resistance,

where,
is resistivity, A is the area and l is the length of the resistor.
It is given that:

Length, l=2 mm
Area, 
Hence, 
We know, Power, 



We know, Voltage,
