A resting heart rate is usually around 40 beats per minute (Thats the normal amount)
The energy discharged at the time of nuclear fusion or fission, mainly when used to produce electricity is known as nuclear energy. Although nuclear energy has become one of the most potent sources of energy in the present time, it also brings some harmful effects along with it, mainly by affecting the surrounding environment like the water bodies present nearby.
Some of the potential problems for the nearby water sources when using nuclear energy are:
1. It contaminates water with radioactive waste.
2. It creates hazardous conditions for the species living in the water.
3. It adds very hot water to cool water environments.
4. It utilizes a resource, which becomes scarce at the time of drought.
n = number of mole of sample of helium gas = 7.16 x 10⁻⁴ moles
T = temperature of the gas = temperature of the bulb ?
V = Volume of helium gas = 75 mL = 7.5 x 10⁻⁵ m³
P = pressure of the helium gas = 116.8 kPa = 116.8 x 10³ Pa (1 k = 1000)
Using the equation
P V = n R T
inserting the values
(116.8 x 10³) (7.5 x 10⁻⁵) = (7.16 x 10⁻⁴) (8.314) T
T = 1471.6 C
Answer:
There are 5.69*10²⁴ molecules in 9.45 moles.
Explanation:
The mole is defined as the amount of matter that particles have, that is, atoms and elementary entities.
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole and represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.
Then the following rule of three can be applied: if 1 mole contains 6.023 * 10²³ molecules, 9.45 moles, how many molecules will it have?
Solving:
amount of molecules= 5.69*10²⁴⁴ molecules
<u><em>There are 5.69*10²⁴ molecules in 9.45 moles.</em></u>
