Hey there!
The molar mass of magnesium is 24.305 grams.
The molar mass of an element is the same as the atomic mass of an element, but measured in grams.
It's on the periodic table underneath the element symbol.
Hope this helps!
I found this on google
“The periodic table is important because its is organized to provide a great deal of information about elements and how they relate to one another in one-easy-to-use reference. The table can be used to predict the properties of elements, even those that have not been discovered.”
I hope this helps
Chloroacetic acid is stronger than acetic acid because of the electron-withdrawing effect of chlorine. This effect is caused by the electronegativity.
Answer:
The correct answer is 0.25 moles/liter
Explanation:
Molarity is a measure of concentration and is defined as the moles of solute in 1 liter of solution.
2 L solution-----0,5 moles of CaO
1 L solution -----x= (1 L solutionx0,5 moles of CaO)/2 L solution =
<em>x=0, 25 moles of Cao ---> 0,25M</em>
