8.21 L of C3H8(g) Lets take c as the molar volume at that temperature.
c L <><> 5c L
C3H8 (g) + 5O2 (g) --> 3CO2 + 4H2O + Q
8.21 L <><> x L
x = (8.21 * 5c)/c = 8.21 * 5 = 41.05 L O2 consumed for a 100% yield.

Answer:

pH = 11.7

Explanation:

Given:

[OH-] = 0.00500 M

To determine:

pH of the solution

Explanation:

pH refers to the H+ ion concentration in a given solution whereas pOH indicates the OH- ion concentration.

pH and pOH are related by the following equation:

$pH + pOH = 14 ------(1)$

Here:

$pH = -log[H+]\\\\pOH = -log[OH-]$

When OH- = 0.00500 M

$pOH = -log(0.00500) = 2.30\\$

Based on equation(1):

$pH = 14 - pOH = 14 -2.30=11.7$
