For 0.0450 mol,

Answer:
the answer of this question is 0.000058
Answer:
since that's the closest option we have
10.6atm
Explanation:
Since volume is constant
P1/T1 = P2/T1
P1 =8.5atm
T1 = 59.2°C = 332.2k
T2 = 140°C = 413k
P2 = ?
8.5/332.2 = P2/413
0.026 = P2/413
P2 = 0.026 x 413
P2 = 10.74atm
the answer is body fossils which is B) body
Answer:
1.772 mols
Explanation:
Because hydrogen exists as a diatomic molecule in gaseous state, that's (H2), so then it's molecular mass is 1 ×2= 2g/mol.
we can now calculate for the number of moles, so
n=m/Mr
n=3.544/2
n=1.772mols
