Answer:
The average atomic mass of element X is 17.561 u.
Explanation:
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
.....(1)
We are given:
Mass of isotope X-17 = 17 u
Percentage abundance of isotope X-17 = 65.20 %
Fractional abundance of isotope 1 = 0.6520
Mass of isotope X-18 = 18 u
Percentage abundance of isotope X-18 = 13.50 %
Fractional abundance of isotope X-18 = 0.1350
Mass of isotope X-19 = 19 u
Percentage abundance of isotope X-19 =21.30%
Fractional abundance of isotope X-19 = 0.2130
Putting values in equation 1, we get:
Answer:
B. The same as that for container A
Explanation:
To calculate the average Kinetic Energy per molecule,
Where is the average kinetic energy per molecule and is the Boltzmann constant
From the above equation it is seen that only depends on the temperature of the gas
And since the temperatures of both gases are equal, their average kinetic energy per molecule is the same
Answer:
Yes, correct
Explanation:
velocity, v = 470 m/s
radius, r = 0.15 m
The radial acceleration is the centripetal acceleration which always acts towards the centre of the circular centrifuge.
The formula for the centripetal acceleration is given by
a = 1472666.667
a = 150272.1 g
According to the question, we can get the acceleration as mentioned. So the claim is correct.
The same number of protons. brainliest?(:
