Answer:
227.47 K
Step-by-step explanation:
It mentions Volume, Pressure Grams (to Moles) and Temperature
therefore we need to use the formula PV = nRT
P is pressure v is volume = n is moles r is universal gas constant (0.0821 always) t is temperature
Convert grams to moles to fit formula
5g / grams of CaCO3 (limestone)
5g / 100.09g CaCO3
= 0.05 mol
Now plug all into formula
PV = nRT
(0.747atm) (1.25L) = (0.05mol) (0.0821) ( T )
0.93375 = (0.004105) ( T )
/0.004105 on both sides
227.47 K (Kelvin)
