D = m/v. v = (3)^3 = 27.
D = 27/27. D = 1g/cm^3
Answer:
222.2 grams of CaCl2 in 2 moles
Explanation:
Mole=given mass/gram mass formula
2moles=x/Gram Mass Formula
(Gram Mass Formula of CaCl2):
Ca=40.1
Cl= 35.5 x 2= 71
-----------------------
GFM=111.1
2 moles = x/111.1 g
x=222.2
That's a heterogeneous mixture because not all the molecules are the same
Salt is a non magnetic solid which makes it soluble in water.
-hope that helps lol
