a. Elemental percent composition is the mass percent of each element in the compound.
The formula for mass elemental percent composition = 
(1)
The molecular formula of cisplatin is 
.
The atomic weight of the elements in cisplatin is:
Platinum, 
Nitrogen, 
Hydrogen, 
Chlorine, 
The molar mass of = 
= 
The mass of each element calculated using formula (1):
- Platinum, 
%

b. The given reaction of cisplatin is:
According to the balanced reaction, 1 mole of 
gives 1 mole of .
Now, calculating the number of moles of in 100.0 g.
Number of moles = 
Molar mass of = 
Number of moles of = 
.
Since, 1 mole of gives 1 mole of . Therefore, mass of cisplatin is:
For mass of 
:
Molar mass of = 
Since, 1 mole of gives 2 mole of . Therefore, mass of is:
Atoms that have lost or gained one or more electrons are called ions.
Answer:
no
Explanation:
los materiales sinteticos son aquellos materiales q estan hechos de polimeros sintetilizados o de pequeñas moleculas
Answer:
λ = 1*10⁻¹⁰m
Explanation:
Frequency (f) = 3.0*10¹²MHz = 3.0*10¹⁸Hz
Speed (v) = 3.0*10⁸m/s
Speed (v) of a wave = frequency (f) * wavelength (λ)
V = fλ
Solve for λ,
λ = v / f
λ = 3.0*10⁸ / 3.0*10¹⁸
λ = 1*10⁻¹⁰m
λ = 0.
The radius of the electron's or basically the energy level for which the electron is found orbiting the nucleus of he hydrogen atom, as the principal quantum number tells us primarily the energy level that the electron will be found, is it the 1st, 2nd, and 3rd. The other quantum numbers tells us more specifically as per the subshell of the main shell the electron is in, the spin of the electron etc.
