Answer:
-I dont have a calculator on me but I can explain to you how to do it and you can put it in your calculator
Step-by-step explanation:
-First you have to balance the equation because its not balanced
4Na+2H2O —-> 4NaOH
-After you balance it you have to add up the grams of H2 gas,
-The mass of each element is measured in grams
- You find how many grams each element it by looking at the periodic table and looking at the number at the bottom, thats called the mass
- Afterward if the element mass you are looking for has a small number as its subscript, that means there is more than one, so you must add them together to get the correct amount of grams it has
1+1=2grams
-After that, you take that and convert it to moles
2grams x 1mole/(6.02^23)grams = (unknown) moles
-And finally you convert that answer from moles to liters
(Unknown) moles x 22.4 Liters / 1 mole = FINAL ANSWER
I hope this was helpful, I tried to break it down the best I could for you <3
