The length of the long leg of the triangle is 144 units
<h3>Pythagoras theorem</h3>
Pythagoras theorem is used to solve the sides of a right angle triangle and can be represented as follows;
where
c = hypotenuse
a and b are the other legs.
Therefore,
145² - 17² = b²
b² = 21025 - 289
b² = 20736
b = √20736
b = 144
Therefore, the length of the longer leg of the triangle is 144 units

The weight percent is of caffiene is 7.98%.
There are several ways of expressing concentration in chemistry. One of the methods of expressing concentration is by the use of percentage.
In this case, we want to obtain the percent weight/weight concentration of caffeine in benzene.
From the question, we can see that;
Mass of solute = 6.5 g
Mass of solvent = 75 g
percent w/w = mass of solute/ mass of solute + mass of solvent × 100/1
percent weight of caffeine=
6.5/6.5 + 75 × 100/1 =7.98%

Answer:
2.82 atm
Explanation:
Initial:
V1 = 28 liters, T1 = 450 C = 450 + 273 K = 723 K, P1 = ?
Final:
V2 = 34 liters, T2 = 350 C = 350 + 273 K = 623 K, P2 = 2.0 atm
Use P1 * V1 / T1 = P2 * V2 / T2
so P1 = P2 * (V2/V1) * (T1/T2) = 2.0 * (34/28) * (723/623) = 2.82 atm
