You have 13.42 mL of a .1400 M NaOH solution. How many moles of NaOH were in this?

Number of moles = 0.002 mol

Explanation:

Given data:

Volume of solution = 13.42 mL

Molarity of solution = 0.1400 M

Number of moles of NaOH = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Volume of solution:

13.42 mL (13.42 mL×1 L /1000mL = 0.013 L)

by putting values,

0.1400 M = number of moles / 0.013 L

Number of moles = 0.1400 M × 0.013 L

            M = mol/L

Number of moles = 0.002 mol

answer; the enthalpy of both the return air and the outside air. ;

consider the reaction below.
