The average atomic mass of Sn is 118.71 g/mol
the percentage of heaviest Sn is 5.80%
the given mass of Sn is 82g
The total moles of Sn will be = mass / atomic mass = 82/118.71=0.691
Total atoms of Sn in 82g = ![6.023X10^{23}X0.691=4.16X10^{23}](https://tex.z-dn.net/?f=6.023X10%5E%7B23%7DX0.691%3D4.16X10%5E%7B23%7D)
the percentage of heaviest Sn is 5.80%
So the total atoms of
= 5.80% X ![4.16X10^{23}](https://tex.z-dn.net/?f=4.16X10%5E%7B23%7D)
Total atoms of
=
atoms
the mass of
will be = ![\frac{2.41X10^{22}X124}{6.023X10^{23}}=4.96g](https://tex.z-dn.net/?f=%5Cfrac%7B2.41X10%5E%7B22%7DX124%7D%7B6.023X10%5E%7B23%7D%7D%3D4.96g)
1 calorie is equal to 4.184 Joules.
Oxygen is a liquid under one atmosphere. the boiling point of a substance is the temperature at which vapor pressure of a liquid is equal to the pressure of the surrounding liquid. the boiling point of oxygen at this case is 90.0k. Therefore the temperature of oxygen is 90-273= -183 celsius scale
The substances for moving things is that they are in motion which is Kinetic Energy
do you have anymore numbers to add to this problem??
