Answer:
1.23x10^-6 mole
Explanation:
A clear understanding of Avogadro's hypothesis proved that 1mole of any substance contains 6.02x10^23 atoms. This indicates that 1mole of Ag contains 6.02x10^23 atoms.
Now, 1f 1mole of Ag contains 6.02x10^23 atoms, then Xmol of Ag will contain 7.41x10^17 atoms i.e
Xmol of Ag = 7.41x10^17/6.02x10^23 = 1.23x10^-6 mole
A. 0.12 (mol/L)/s
rate = 1 x 10-2 • 2^2 • 3
4FeS2 + 11O2-> 2Fe2O3 + 8SO2
Not sure.... I think this is it
Distance s=347 meters
time t=134 sec.
speed =s/t=347/134=2.5896 m/s nearly
