Explanation:
Answer:
(C5H7)8
Explanation:
It's empirical formula is given as; C5H7
Molar mass of carbon(C) = 12 g/mol
Molar mass of hydrogen(H) = 1 g/mol
We are told that it's molar mass is 536 g/mol.
To find the molecular formula;
Molecular formula = n × empirical formula
Thus;
n = 536/((12 × 5) + (1 × 7))
n = 8
Thus;
Molecular formula = (C5H7)8
Answer:
There are 146 neutrons in Uranium-238
There are 90 electrons in Thorium-234
That there are empty space in the atom
That almost all of the mass is concentrated at the center of the atom
