Explanation:
The given data is as follows.
No. of moles = 
, V = ?
T = 20.2 + 273 K = 293.2 K, P = 
= 1.046 atm, R = 
Calculate the volume using ideal gas equation as follows.
P V = n R T
V = 
= 
= 
L
Thus, we can conclude that volume of the gas is L.
Answer:The answer is Rosalind Franklin
Explanation:It is the only option that would be correct because the last person had two people for Rosalind and James I think, but Rosalind is definitely the correct answer

Answer:
4 phosphorus
Explanation:
The given compound is:
2Ca₃(PO₄)₂
We have been given 2 moles of Ca₃(PO₄)₂ . The number of atoms is the same as the number of elements present within the compound. Since this is 2 moles, we multiply every number of atoms by 2;
2Ca₃(PO₄)₂
Ca : 2 x 3 = 6 atoms
P : 2 x 2 = 4 atoms
O: 2 x (2 x 4) = 16 atoms
So we have 4 phosphorus atoms
