The new volume of the hot air balloon is 801.9L.
As the temperature of the hot air balloon on the table is increased, the its volume also increases.
<h3>Charle's law</h3>
Charle's law states that the volume of an ideal gas is directly proportional to the absolute temperature provided pressure is kept at constant.
It is expressed as;
V₁/T₁ = V₂/T₂
Given the data in the question;
- Initial temperature T₁ = 26.7°C = 299.85K
- Final temperature T₂ = 48.3°C = 321.45K
To calculate the new volume we subtsitute our given values into the expression above.
V₁T₂ = V₂T₁
V₂ = V₁T₂ / T₁
V₂ = ( 748L × 321.45K ) / 299.85K
V₂ = 240444.6LK / 299.85K
V₂ = 801.9L
The new volume of the hot air balloon is 801.9L.
As the temperature of the hot air balloon on the table is increased, the its volume also increases.

PbCl2--->Pb2+ + 2Cl-
The mass of PbCl2 is =mass of the beaker+Pbcl2 minus mass of the beaker
that is 62.19-57.77g= 4.42grams
moles of PbCl2= 4.42g/278g/m0l = 0.0159moles
concentration of (Pb2+)
since mole ratio of PbCl2 to Pb2+ is 1:1 therefore the moles of Pb2+ is also 0.0159moles
concentration =0.0159/100 x1000=0.159M
concentration of CI- is two time that of Pb2+ from the equation above therefore concentration of Cl- = 0.159 x2 =0.318M
