I believe the answer is: high humidity, warm air temperature, and low air.
Answer:One mole of a substance contains 6.02×10∧23 particles,
1 mole of a aluminium contains 27 g
35 g of aluminium contains 35/27 =1.296 moles
Thus, the number of particles will be 1.296 × 6.02 ×10∧23
= 7.804 × 10∧23 particles,
Hence, 35 g of Aluminium contains 7.804 × 10∧23 atoms

a) 0/17moles
b)1.02x10^23
c) 1.12 x 10^25
Is this correct
Explanation:
Use:
n = m/M
N= n x NA

Answer:
mass of nitrogen dioxide = 368g
Explanation:
From the equation:
2 moles of NO = 2 moles of 2 NO2
4 moles of NO = x moles of NO2
x = (2 × 4)/2 = 8/2 = 4 moles of NO2
No. of moles = reacting mass/ molecular weight
Reacting mass = No. of moles × molecular weight
Reacting mass = 4 × 92 = 368g
