Answer:
2.51 x 1023 atoms C
Explanation:
MW C = 12.011
5g x (1mol/12.011g) =0.416 mol
0.416 mol x (6.022x10^23) = 2.51 x 1023 atoms C
Answer:
false
Explanation:
Only ionic compounds can dissolate in water.
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:

This is not a phospholipid as it does not contain a phosphate group at the end of the chain, and is not a triglyceride as there is no glyceryl moiety. Each carbon bonded to hydrogens makes the maximum number of C-H bonds possible, therefore there are no multiple bonds between carbons and the lipid is saturated. Therefore the answer is A.
