Answer:

HCOOH(aq) + OH-(aq) —> HCOO-(aq) + H2O(l)

Explanation:

HCOOH is a weak acid and so will not ionised completely in solution.

KOH is a strong base and will ionised completely as shown below

KOH(aq) –> K+(aq) + OH-(aq)

The overall reaction can be written as follow:

HCOOH(aq) + K+(aq) + OH-(aq) —> HCOO-(aq) + K+(aq) + H2O(l)

Cancel out the K+ to obtain the net ionic equation as shown below

HCOOH(aq) + OH-(aq) —> HCOO-(aq) + H2O(l)

How many grams of sodium chloride are required to prepare 500.0 ml of a 0.100 m solution?
scoray [572]

Answer:

  • <u>2.92 g</u>

Explanation:

<u>1) Data:</u>

a) V = 500.0 ml = 0.500 liter

b) M = 0.100

c) mass = ?

<u>2) Formulae:</u>

a) Molarity: M = n / V

b) Number of moles: n = mass in grams / molar mass

<u>3) Solution</u>

a) M = n / V ⇒ n = M × V = 0.1000 M × 0.500 liter = 0.0500 mol

b) molar mass NaCl = 58.443 g/mol

c) mass = n × molar mass = 0.0500 mol × 58.443 g/mol = 2.92 g

Answer: 2.92 g
