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, %
%.
- Nitrogen, %
%
- Hydrogen, %
%
- Chlorine, %
%
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:
Because their molecules are more tightly packed. Massdensity = ---------- Volume
So more densely packed molecules means more mass per unit volume. Hence metals are denser than non-metals.
Answer:
glucose and oxygen
Explanation:
plants use carbondioxide, water and sunlight to produce their food through photosynthesis so in return they produce oxygen into the air as by product and glucose
The answer is B charged particles
Answer:
no
Explanation:
Radium is silvery, lustrous, soft, intensely radioactive. It readily oxidizes on exposure to air, turning from almost pure white to black. Radium is luminescent, corrodes in water to form radium hydroxide. Although is the heaviest member of the alkaline-earth group it is the most volatile.
