I believe you meant 88.1 grams and not moles. To solve this, you would simply need to divide the grams by the molar mass of Magnesium which can be found on any periodic table. Note that molar mass is in grams/mol so grams will cancel out leaving you with mol. For instance, Oxygen has a molar mass of 16 grams/mol, but O2 has a molar mass of 32 grams/mol since you have a molecule containing 2 O's.
Hi, Rosala! Thanks! Glad to see you and everyone else again, too!
As always, lots of comical images! The education one stood out to me...reminds me of the education system here...it really does need modification...
The last image reminds me of women and STEM (science, tech, engineering, math). That is a powerful quote!!!
This requires stoichiometry.
Find the molar mass (g/mol) of Magnesium and Magnesium Oxide by using the periodic table.
Then, simply use dimensional analysis to solve for mass of MgO.
Start with the given information and convert from there. Also, note the mole ratio is 2:2 or 1:1.
0.52g * (mol / # g Mg) * (2 mol MgO / 2 mol O) * ( # g MgO / mol) = ?
Thanks DS and Chris!
I am doing alright. Just lots of things happening these days and yes, it is good...the usual. Right now, no grades yet since it just started. I'm glad to be back as well. Will visit from time to time!
However, the weather is crazy here...it is in the 90s (Fahrenheit) in October! I am going crazy.
