To calculate moles from grams using chemical formulas ... However, one mole of magnesium weighs 24.31 g. ... 0.873 g x 95.21 g = 9.17 x 10-3 mol MgCl2.
I love chem!!! Hopefully I got it right for u I got
In the calculator: 7.127272727
But if u need it in sig figs: 7.1atm

Explanation:
Answer:
The answer is B
[The extracting solvent should be non-toxic and readily available]
Explanation:
The extracting solvent should not pose a risk to life (or the risk have to be minimum) and be available in large quantity.
A. Most of the extracting solvents are volatile, and is a good think because you can remove them by distillation.
C. The extraction solvent should <u>not</u> react with the solute, because you lose the extracted compound.
D. The extraction solvent should <u>not</u> be miscible with water. Usually you extract compounds organic compounds from water using an appropriate extracting solvent.
Answer:
0.47dm³
Explanation
Given parameters :
Molarity of NaCl = 6.67M
Number of moles = 3.12mol
Volume of NaCl =?
Volume of NaCl = number of moles/Molarity
Volume of NaCl = 3.12mol/6.67M
Volume of NaCl = 0.47dm³
