Magnesium: Chlorine and Hydrogen Moles

 Magnesium: Chlorine and Hydrogen Moles Analysis Paper



The main purpose for this experimental lab is usually to determine the atomic fat of magnesium, as well as an underlying purpose in determining the relationship between moles evolved and consumed.

This is often demonstrated by simply measuring the hydrogen gas evolved by performing a chemical research when hydrochloric acid responds with the magnesium (mg). The created reaction includes; Mg & 2HCl в†’ H2 + Mg2+(aq) + 2Cl- (aq)

The major findings contributing to the experiment has been able to determine and differentiate what skin moles have evolved thus becoming the hydrogen moles advanced allowing the magnesium to be consumed in the reaction.


Step 1 :

Obtain a six-hundred mL beaker, and add three hundred mL of water.


Add 31 mL of HCl (2M) to the beaker, and blend.

Step 3.

Add 10 magnesium of magnesium (mg) metal to the beaker.

Step 4.

Permit the hydrogen gas to develop. All of the magnesium (mg) should be used. Step 5.

Record the number of hydrogen gas that has developed using the substance property discussion.

Observations and Results

Moles of hydrogen evolved: zero. 000411 (4. 11 by 10-4th) moles of H2 evolved

Calculated atomic weight of magnesium: Fat of Magnesium /moles of H2 progressed

[24. 305g/mol / 0. 000411 = fifty nine, 136. 25 g/mol of Mg]

As I extended with my own experiment I came across a few observations that are important to bring to focus. As I added 10 mg of magnesium (mg) to the beaker of HCl, a not getting sun area made an appearance at the bottom in the beaker. Straight after, bubbles formed in the same beaker thus implying the Mg was being consumed.


The moles of hydrogen gas which have evolved throughout the experiment led to 0. 000411.

The calculated atomic weight of magnesium depends upon the mixture of; atomic pounds of Mg (in grams)=weight of Mg consumed (in grams) as well as moles of H2 evolved, therefore the equation should be such as this; [24. 305g/mol as well as 0. 000411 = 59, 136. 25 g/mol of Mg].
