Answer:
0.315 atm
Explanation:
PV = nRT
P(96.2) = (1.24)(0.08206)(25 + 273)
P = 0.315 atm

n (NaOH) = ------
1000
0.1 × 500
n (NaOH) = ----------------
1000
n (NaOH) = 0.05 moles
Mass= Mr(NaOH) × moles
Mass= (23+16+1) × 0.05
Mass=2.15 g (2.15 grams)

B: element A
C: element B
D: element A
Explanation:
