Basic radicals (cations) have been divided into groups based on Ksp values
Molar mass:
O2 = 16 x 2 = 32.0 g/mol Mg = 24 g/mol
<span>2 Mg(s) + O2(g) --->2 MgO(s)
</span>
2 x 24.0 g Mg -------------> 32 g O2
5.00 g Mg -----------------> ( mass of O2)
mass of O2 = 5.00 x 32 / 2 x 24.0
mass of O2 = 160 / 48
= 3.33 g of O2
hope this helps!
Answer:
The answer is 1385 x10∧ -3
Explanation:
Scientific notation is a quick way to represent a number using notation in exponential form or powers of base ten.
This notation allows us to express too large or small numbers easily.
<u>For example:
</u>
500 is written as 5x10∧2; Where the power 2 represents the number of 0's that follow 5.
0.0093 is written as 9.3x10∧-3; Where the power -3 represents the number of times the comma was moved to the right.
There are two carbon atoms in every ethanol molecule, so there would be 60 carbons all together.
I hope this helped you!
