Answer:
173.8g
Explanation:
STP means standard temperature and pressure
The temperature there is 273k while the pressure is 1 atm
now we are to use the ideal gas equation to get the number of moles first
Mathematically;
PV = nRT
here P = 1 atm
V = 88.5 L
n = ?
R = molar gas constant = 0.082 L atm mol^-1 K^-1
Now rewriting the equation we can have
n = PV/RT
plugging the values we have
n = (1 * 88.5)/(0.082 * 273)
n = 88.5/22.386
n = 3.95 moles
Now we proceed to get the mass
Mathematically;
mass = no of moles * molar mass
molar mass of carbon iv oxide is 44g/mol
mass = 3.95 * 44 = 173.8 g

francium , in the Periodic table the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. making helium is the smallest element, and francium the largest.
...acid rain can eat away metals, it’ll corrode them, but to affect the rate?? I’m pretty sure some elements can neutralize acid, perhaps slow down its reaction, like limestone for example. A lake lined with limestone will neutralize any acid fallen into the water. But as for a statue, I’m not sure but it must be something similar... sorry I can’t be more of a help :\
