How would I calculate the mass of this?
Posted by admin | Filed under Chemistry
I need help with my chemistry homework.
How do I calculate the mass of 2.0 moles of BaCl(small lowered 2)2H(small 2)O?
If you have questions about the question email me at shoppergal180@gmail.com
Please show me how to do this with work so I can figure out the rest of my problems.

Use a factor label method. Start with what they give you.
244.25 g / mol is the molar mass of BaCl2 . 2H2O (137.33 + 2(35.45) + 2(18.02))
2.0 mol BaCl2 . 2H2O x (244.27 g / 1 mol) = 488.54 g BaCl2 . 2H2O
