The total number of particles present in 12.7 moles of the compound owned by Jessica is 7.65 x10^24 particles of the compound (response E)
Calculation Steps
The total number of particles is determined through Avogadro's Principle constant.
- This principle states that Avogadro's 1 mole equals 6.02 x10^23 particles
So, how many particles correspond to 12.7 moles of the compound? particles\
By applying cross multiplication, the formula yields: particles of the compound= [12.7 moles x (6.02 x 10^23)] / 1 mole
= 7.65 x 10^24 particles of the compound (response E)
moles cancels each other out.
The solution to your inquiry yields P = 17.73 atm. Explanation: The volume V is 250 ml, equivalent to 0.25 liters (L), with a mass of 3.4 g and a temperature of 45°C, which converts to 318°K. We utilize the ideal gas law PV = nRT for the calculations.
The resulting temperature is 46.5°C.
Details:
According to Charles's law, the volume of gas, while maintaining constant pressure, correlates directly with temperature in Kelvin.
The formula representing Charles's law is expressed as follows:
We need to determine T2, thus:
V1 = 736 ml = 0.736 L
T1 = 15 ° C
V2 = 2.28 L
Substituting the values gives us:
T2 = 
= 46.5°C
It is evident that as the volume increases, the temperature also rises.
E = mc²
where E = energy produced
m = mass of the nucleus
C = speed of light
m = 9.106 x 10⁻³ x 1.67 x 10⁻²⁷ kg
C = 3 x 10⁸ m/s, thus C² = 9 x 10¹⁶
E = 1.37 x 10⁻¹² J
Ca3(PO4)2 is the correct formula.
