Answer:
5.77 L
Solution:
Data Given:
Moles = n = 0.24 mol
Temperature = T = 35 °C + 273 = 308 K
Pressure = P = 1.05 atm
Volume = V = ?
Formula Used:
Let's assume that the hydrogen gas in balloon is acting as an Ideal gas, the according to Ideal Gas Equation,
P V = n R T
where; R = Universal Gas Constant = 0.082057 atm.L.mol⁻¹.K⁻¹
Solving Equation for V,
V = n R T / P
Putting Values,
V = (0.24 mol × 0.082057 atm.L.mol⁻¹.K⁻¹ × 308 K) ÷ 1.05 atm
V = 5.77 L
Answer:
<h3>The answer is 14036.54 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula

where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 8.45 x 10^27 molecules of H2O
We have

We have the final answer as
<h3>14036.54 moles</h3>

Gamma rays
gamma rays has shortest wavelength which emits from the sun so it has highest energy because energy and wavelength are inversely proportional to each other.
