need help with both
Explanation / Answer
Question 13
Option A (41.9 ml) is the answer
PV = nRT
P= 0.921 atm V = 50 ml or 0.05 Liter n = ?
R = 0.0821 L atm K-1 Mol-1 T = 27 + 273 = 300K
FInd n
0.921 x 0.05 = n x 0.0821 x 300
n = 0.001869 Mole
Use the same equation to find Volume at STP
1 x V = 0.001869 x 0.0821 x 273
V = 0.0419055 Liter = 41.9 ml
Question 14
PV = nRT
Temperature and Pressure are directly propotional to each other.
Hence Option A Increases is the answer
