Answer:
4
Explanation:
The zeros before a non zero digit do not count as significant figures so there are 4 sig figs in the number
I believe it is C, but I can't guarantee it.
Answer:The farming methods promoted by the California Ricelands Habitat Partnership are best described as beneficial to both farmers and wetland species because California Rice Commission and individual growers to further enhance the habitat [ value of California’s rice fields to waterbirds. This collective approach creates synergy for fully realizing the wildlife values in California rice
Explanation:
First, we will calculate the entropies as follow.
J/K mol
As,
= 298 K,
= 373.8 K
Putting the given values into the above formula we get,
J/K mol
=
= 18.5 J/K mol
Now,

= 
= 94.2 J/mol K
Also,
= 
= 33.4 J/K mol
Now, we will calculate the entropy of one mole of methanol vapor at 800 K as follows.

= (126.8 + 18.5 + 94.2 + 33.4) J/K mol
= 272.9 J/K mol
Thus, we can conclude that the entropy of one mole of methanol vapor at 800 K is 272.9 J/K mol.
