2 AnswersPhysics1 decade agofinding moles and name of the element?
. The problem statement, all variables and given/known data
a sample of 0.6 moles of a metal M reacts completely with excess of flourine to form 46.8 gms of MF2.
a)how many moles of F are present in the sample of MF2 that forms?
b)which element is represented by the symbol M?
2. Relevant equations
NO. OF MOLES=given mass/molar mass
3. The attempt at a solution
molesof element M:moles of compound formed MF2
1 : 1
0.6 : 0.6
1 mole of MF2 contains 2 moles of F
0.6 MOLES WOULD CONTAIN=0.6*2=1.2
now i dnt no how can i find which element it is
