No, you don't multiply the molar mass of silver by 2. You've already got the number of moles of Ag ions. All you need to do is multiply it by Ag's molar mass.x.Exhaust.x said:Ah, I found the molar mass of Ag2SO4, rather than finding the molar mass of silver and multiplying by 2. Now I've realised I need more work with my calculations.
Thanks.
:uhhuh::uhhuh::uhhuh:x.Exhaust.x said:Sorry, I meant multiplying the moles of silver ions by 2 (2x10-6 mol Ag+), then finding the molar mass of silver through the periodic table, and finally, calculating the mass through the calculation.

Beryllium fluoride is the chemical compound with the formula BeF2. It is the binary beryllium compound with the greatest amount of ionic character (due to the high electronegativity of fluorine), but even so it is not considered ionic by many chemists.
Probably has properties of both. Like the quantum theory. Is light wave or particle?x.Exhaust.x said:http://en.wikipedia.org/wiki/Beryllium_fluoride
I did. It didn't really state specifically whether it was ionic or covalent.
It's considered covalent. If you looked at the electronegativity difference however, you would assume it's ionic because the different is greater than 2 (should be, though I didn't check). However, Be is a special atom because it doesn't obey the octet rule (B is the other one).bubblesss said:thanks so its a special case but is it considerd as ionic or covalent??
It's actually a semi-metal.bubblesss said:how does boron become an exception? isn't it just a non-metal?
