We are given the molar mass of Molybdenum as 95.94 g/mol. Also, the chemical symbol for Molybdenum is Mo. This question is asking for the amount of molecules of molybdenum in a 150.0 g sample. However, since molybdenum is a metal and it is in the form of solid molybdenum, Mo (s), it is not actual a molecule. A molecule has one or more atom bonded together. We will instead be finding the amount of atoms of Molybdenum present in the sample. To do this we use Avogadro's number, which is the amount of atoms/molecules of a substance in 1 mole of that substance.
150.0 g Mo/ 95.94 g/mol = 1.563 moles of Mo
1.563 moles Mo x 6.022 x 10²³ atoms/mole = 9.415 x 10²³ atoms Mo
Therefore, there are 9.415 x 10²³ atoms of Molybdenum in 150.0 g.
If bath bomb is put into contact with water, they will then fizz up because of the ingredients which are citric acid and bicarbonate soda.
To find the number of neutrons.....
NEUTRONS = MASS NUMBER - ATOMIC NUMBER ( PROTONS)
NEUTRONS = 19 - 9
So this element has 10 neutrons
Answer: The rate will increase by a factor of 9.
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
Given: Order with respect to = 2
Order with respect to = 1
Thus rate law is:
k= rate constant
It is given that the initial concentration of NO is tripled while all other factors stayed the same
Thus the rate will increase by a factor of 9.
