Answer:
0.315 atm
Explanation:
PV = nRT
P(96.2) = (1.24)(0.08206)(25 + 273)
P = 0.315 atm
1.09 moles of tin (Sn)
Explanation:
We have the following chemical reaction where tin chloride (SnCl₂) reacts with sodium (Na) to produce tin (Sn) and sodium chloride (NaCl):
SnCl₄ + 4 Na → Sn + 4 NaCl
Taking in account the chemical reaction, we devise the following reasoning:
if 1 mole of SnCl₂ will react with 4 moles of Na
then 2.34 moles of SnCl₂ will react with X moles of Na
X = (2.34 × 4) / 1 = 9.36 moles of Na
So, 2.34 moles of SnCl₂ will react with 9.36 moles of Na but we only have 4.36 moles of Na available. The limiting reactant will be Na. Knowing this we devise the following reasoning:
if 4 moles of Na produces 1 mole of Sn
then 4.36 moles of Na produces Y moles of Sn
Y = (4.36 × 1) / 4 = 1.09 moles of Sn

PH is a scale used to measure the acidity or alkalinity of an aqueous solution. It can be used to calculate the amount of hydronium ions in the solution. It is expressed as the negative logarithm to the base 10 of the concentration.
pH = -log [H+]
2.0 = -log [H+]
[H+] = 0.01 M
