Answer:
m = 19 grams
Explanation:
Given that,
No. of moles, n = 0.8
The molar mass of magnesium, M = 24.305 u
We need to find the mass of 0.80 moles of Mg. We know that given mass to the molar mass is equal to no of moles. Let the mass is m. So,
or
m = 19 grams
So, the mass of 0.8 moles of Mg is 19 grams.
Ur answer is A

is the Calcium
because the calcium in group two which group two has 2 electron and also calcium and Potassium 4s sub level group potassium has 1 electron. :)
Answer:
Silicon is one of the highest quality semiconductors that is ideal for solar cell production. The superior quality of silicon’s electronic, optical, thermal, and environmental properties are best for producing solar cells. Also, the availability and affordability make it more usable for solar panels.
These are the five properties. Hopefully, this helps! :)
Your chemical formula of glucose is messed up. It is C6 H12 O6.
So, to get it, you simply multiply the number of atoms of C H and O by their atomic weights each and add all of them together to get the molar mass of glucose.
