Answer:
Explanation:
entire mixture = 5.32g
F = 3.12g --> 3.12g*(1mol/18.998g) = 0.1642mols F
Since LiF has 1mol Li to 1 mol F,
0.1642mols F* (1mol Li/1 mol F) = 0.1642mols Li
Convert into grams:
0.1642mols Li * (6.94g/1mol) =1.1397g Li
So add the masses of Li and F together:
3.12g F + 1.1397g Li = 4.2597g LiF
5.32g - 4.2597g LiF = 1.06g KF
-----
Basically what we did is convert the given mass of F to mols and since we know that there is a 1:1 mole ratio of F to L, the number of mols of F is the number of mols of Li. Change the mols of Li to grams and then add the mass of Li with given mass of F. You now have the mass of LiF. To find mass of KF, subtract mass of LiF from mass of entire mixture.
The smallest volume from among the following is <span>0.012L.</span>
Refers to the number of neutrons in the nucleus of an atom
Liquid, in a liquid state of matter, particles will flow over eachother, the forces between the particles are strong enough to hold a certain volume but not strong enough to keep the molecules sliding over each other.
