iVinArrow [24]3 years ago
4 0

First, we write the reaction for CH3OH combustion

CH3OH+3/2O2--->CO2+2H2O

for 1 mole of methanol, we get 1 mole of CO2, therefore for 5,25 moles of methanol we will get 5,25 moles of CO2

Leviafan [203]

Answer:

The unknown NaOH base has a concentration of 0.636M

Explanation:

<u>Step 1:</u> the balanced equation

NaOH + HCl → NaCl + H2O

This means for 1 mole of NaOH consumed there is 1 mole of HCl needed to produce 1 mole of NaCl and 1 mole of H2O

<u>Step 2</u>: Calculate moles of HCl used

Number of moles = Concentration *  volume =  0.5M * 25*10^-3 L =0.0125 moles

<u>Step 3</u>: Calculate moles of NaOH

Since the mole ratio for HCl and NaOH is 1:1 this means we have 0.0125 moles of NaOH for 0.0125 moles of HCl

<u>Step 4:</u> Calculate Concentration of  the unknown NaOH base

Concentration = Number of moles / Volume

Volume of NaOH = 24.64-5 =19.64 mL = 0.01964 L

Concentration = 0.0125/0.01964 = 0.636 M

The unknown NaOH base has a concentration of 0.636M
