Answer:
A) 9.60 g
B) 19.2 g
C) 28.8 g
Explanation:
A) Elemental oxygen mass is 16.00 g/mol, so in 0.600 mol of elementar oxygen there is 9.60 g
0.600 mol x 16.00 g/mol=9.60 g
B) Oxygen molecular mass is 32.00 g/mol, so in 0.600 mol of oxygen molecules there is 19.2 g
0.600 mol x 32.00 g/mol=19.2 g
C) Ozone molecular mass is 48.00 g/mol, so in 0.600 mol of oxygen molecules there is 28.8 g
0.600 mol x 48.00 g/mol=28.8 g
Answer:
N-terminal Phe, C-terminal Ser
Explanation:
Amino acids connect like
NH2 -CH(R1) -CO -NH-CH(R2)-CO-.....-NH-CH(Rn)COOH
So, 1st amino acid is N -terminal , and it is Phe.
Last amino acid is C- terminal, and it is Ser.
Answer: __3__Na2CO3 + __2__Ag3P → __2__Na3P + __3__Ag2CO3
Explanation:
In balancing equations you need to make sure the number of atoms before the reaction should be equal to the number of atoms after the reaction.
Before the reaction: We had 6Na, 9CO, 6Ag and 2p
After the reaction: We have 6Na, 9CO, 6Ag and 2p
And now we are sure that atoms before the reaction are equal to atoms after the reaction
(1.1232 * 10⁵) (6.022 * 10¹⁷)
Now, multiply simple numbers together and exponentials, together:
= 1.1232 * 6.022 * 10⁵ * 10¹⁷
= 6.763 * 10²²
In short, Your Answer would be 6.763 * 10²²
Hope this helps!
