Find the mass in 2.6 mol of lithium bromide
I got 225.797g Explanation I found the mass of the whole compound by adding up the mass numbers of LiBr. This gave me 86.845. I then multiplied that by the 2.6 and that gave me 225.797
2.6 mol LiBr (86.8 g LiBr/ 1 mol LiBr)= 2.310^2 g LiBr.The mass of LiBr is 2.3*10^2 g~
