Calculate the Experimental Molar Volume in L/mol of the Hydrogen gas, H2, if the volume of H2 at STP is 52.8 mL and the mass of Magnesium metal, Mg, used in the experiment is 0.055 g.

The Experimental Molar Volume in L/mol of the Hydrogen gas=23.36L/mol

Explanation:

We are given that

Volume of H2 at STP=52.8mL

Mass of magnesium metal ,M(Mg)=0.055g

We have to find the Experimental Molar Volume in L/mol of the Hydrogen gas.

Molar mass of Mg=24.305 g/mol

Number of moles=

Using the formula

Number of moles of Mg=moles

Number of moles of Mg=0.00226moles

Number of moles of Mg=Number of moles of H2

Number of moles of H2=0.00226moles

Molar volume of Hydrogen gas (H2)=

Molar volume of Hydrogen gas (H2)=

Molar volume of Hydrogen gas (H2)=

Molar volume of Hydrogen gas (H2)=23.36L/mol

Hence, the Experimental Molar Volume in L/mol of the Hydrogen gas=23.36L/mol

I dont know if this is the right subject but i got an A+ on it. It is Life science edgenuity     This is the process part of it

Explanation:

First, I observed all of the arthropods that I would be using in my dichotomous key, Fire Ant, Bee, Butterfly, Dragonfly, Ladybug, Scorpion, Spider, and Wasp. I recorded my observations on a characteristics table that included Legs, Wings, Stinger, Antennae, and Claws.  

Next, I used my observations to create my first question, “Does the arthropod have a stinger?).  

     Then, I Looked over my notes and found the arthropds that have stingers, Fire Ant, Bee, Scorpion, and        Wasp, and sorted them into a Yes group. Also I found the arthropods in my notes that didn’t have stingers, Butterfly, Dragonfly, Ladybug, and Spider, and put them into a No group.  

     After That, I Chose a new question coming off of the Yes group, “Does the arthropod have 6 legs?”. I sorted those the arthropods that did have 6 legs into a Yes group, Fire Ant, Bee, and Wasp.  

     Then, I did the same for The arthropods who didn’t have 6 legs and the only one was Scorpion, so I wrote scorpion in the No group and that Branch was done.  

     Next, I did another question for my very first No group, “Does the arthropod have antennae?” and I sorted the arthropods into the yes and no branches. No group included, Dragonfly and Spider. Yes group included, Butterfly and Ladybug.

     Later, I did a question for the yes group coming off of the 6 legs question, “Does the arthropod have wings?”. The yes group included, Bee and Wasp. The no group included, the Fire Ant only so I wrote down Fire Ant and that branch was concluded.  

     Then, I did a question for the no group coming off of the antennae question, “Does the arthropod hve 8 legs?” and my yes group included spider only so that branch was done. My no group included Dragonfly so that branch was concluded aswell.  

     After That, I wrote a question for the yes group coming off of the wings question, “Does the arthropod have 2 wings?”. My Yes group concluded wit only the Wasp left so I had finished that branch. I finished my no group with a Bee.

     Lastly, I did my last question of the key coming off of the Yes group of the antennae question, “Does the arthropod have 4 wings?”. My no group included a Ladybug and my yes group included a Butterfly.

     In conclusion, My dichotomous key was finished with 8 athropods in each branch alone and now you can use the dichotomous to observe a Fire Ant, Bee, Wasp, Butterfly, Dragonfly, Ladybug, Spider, and Scorpion.
