Given 40 grams of magnesium. How many mole is this
Dahasolnce [82]

To determine the moles in 40 grams of magnesium, we need the atomic weight. This can easily be found on a periodic table. For this problem, let's use 24.305 grams/mole.

We are going to set up an equation to determine this problem. In this equation, we want all our units to cancel out except for 'moles.'

\frac{40 g Mg}{1} x\frac{1 mole Mg}{24.305 g Mg}

In this, we can see that the unit 'grams' will cancel out to leave us with moles.

In solving the equation, we determine that there are approximately 1.65 moles of Magnesium.

statuscvo [17]
The given acid is HCOOH, it is dissociated in water. This balanced equation represents the dissociation of HCOOH in water:

HCOOH + H2O ---> H+ + COOH-

The Ka of HCOOH is:

Ka = concentration of products / concentration of reactants

Ka = [COOH-] [H+] / [HCOOH]
