Answer:
V₂ = 495.89 mL
Explanation:
Given data:
Initial number of moles = 0.213 mol
Initial volume = 652 mL
Final number of moles = 0.162 mol
Final volume = ?
Solution:
V₁/n₁ = V₂/n₂
By putting values,
652 mL/0.213 mol = V₂ /0.162 mol
V₂ = 652 mL 0.162 mol /0.213 mol
V₂ = 105.62 mL.mol /0.213 mol
V₂ = 495.89 mL
By use of gay lussacs law
state b that for a given mass and constant volume of an ideal gas .the pressure exerted on the side of its container is directly proportional to its obsolute temperature
T2= (p2 x T1)/P1
(1800 x250) / 1200= 375K
Calories per gram are released by the burning Dorito is 1.4 cal/g.
<h3>What are calories?</h3>
Calories are a measurement of the energy content in foods.
Foods such as containing fats are rich in calories.
The amount of calories released per gram y the burning Dorito id determined using the formula below:
- Calories = (mass of water)(temp change of water)(0.001 Cal/g°C)
mass of water = 10 g
temperature change = 35°C
Calories = 10 * 35 * 0.001
Calories = 0.35 calories
mass of Dorito burnt = 1.25 - 1.00 = 0.25g
Calories per gram are released by the burning Dorito = 0.35 calories/0.25 g
Calories per gram are released by the burning Dorito = 1.4 cal/g
In conclusion, the energy released by burning foods are given in calories.
