How much NaOH (in grams) is needed to prepare 463 mL of solution with a pH of 10.020?

tino4ka555 [31]

Answer: $1.94\times 10^{-3}g$ of NaOH

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

$pH=-\log [H^+]$

Putting in the values:

$10.020=-\log[H^+]$

$[H^+]=9.55\times 10^{-11}$

$[H^+][OH^-]=10^{-14}$

$[OH^-]=\frac{10^{-14}}{9.55\times 10^{-11}}=1.05\times 10^{-4}M$

$NaOH\rightarrow Na^++OH^-$

$Molarity=\frac{moles\times 1000}{\text {Volume in ml}}$

$1.05\times 10^{-4}M=\frac{moles\times 1000}{463ml}$

moles = $4.86\times 10^{-5}$

Mass of $NaOH=moles\times {\text {Molar mass}}=4.86\times 10^{-5}\times 40=1.94\times 10^{-3}g$

Thus $1.94\times 10^{-3}g$ of NaOH is needed to prepare 463 mL of solution with a pH of 10.020

Determine the density of nh3 gas at 435k and 1.00atm

goldenfox [79]

We assume that this gas is ideal. Therefore, we can use the ideal gas equation which is expressed as:

PV=nRT

We manipulate this equation to give us an expression which will correspond to density. We do as follows:

PV= nRT
P/RT = n/V where n = m/MM
P(MM) /RT = m/V = density
Density = 1.00 (17.03) / 0.08206 (435)
Density = 0.48 g / L
