3/4 or 4/4 would be the answer because if you use 1/4 out of 4/4 you would either have an answer of 3/4, 4/4 or 1. The 1 because 4/4 is equal to 1.
The answer would be 6.023 x 10E23
E= exponent
<span>The correct formula for Beryllium phosphate is Be3(PO4)2
Beryllium has a charge of +2 and phosphate has a charge of -3. So to make the charge equal to zero, 3x +2 = 6, and 2 x-3 = -6
-6 + +6 = 0</span>
