The pressure of 2.29 atm can be converted to
Conversation is a way of writing a value in another unit, it helps to reduce large values by using a unit.
It should be noted that 1 atm. =760.0 mm Hg
We were given 2.29 atm, the we can convert it to mm Hg. as;
= 1740.4 mm Hg.
Therefore, The pressure of 2.29 atm can be converted to

Answer:
Explanation:
Na₂S₂O₃ solution does not react with KI (it reacts with I₂), so it is simply diluting the KI, and we can use the dilution formula.
Data:
c₁ = 0.15 mol·L⁻¹; V₁ = 5 drops
V(Na₂S₂O₃) = 40 drops
Calculations:
(a) Calculate the total volume
V₂ = 5 + 40 = 45 drops
(b) Calculate the concentration
0.15 × 5 = c₂ × 45
0.75 = 45c₂
