<em />If 100 brownies require 6 eggs, 5 cups of flour, and 2 sticks of butter. Then, 50 brownies should require half of those required to make 100 brownies. Use ratio and proportion to determine the number of eggs needed:
100/50 = 6/x
x = 3<span />
Answer:
7.35 atm
Explanation:
From the question we are given;
- Initial volume, V1 as 28 L
- Initial temperature, T1 as 42°C or 315 K
- New volume. V2 as 49 L
- New temperature, T2 as 27°C or 300 K
- New Pressure, P2 as 4.0 atm
We are required to determine the initial pressure, P1
We are going to use the combined gas law...
According to the combined gas law,
Therefore, to get P1
We get;
Therefore, the initial pressure of the gas is 7.35 atm
