Type the numerical answers to these questions to 3 significant figures (no units required).
To enter 1.23 x 10-4 simply type 1.23 x 10-4.
What is [PO43-] of a solution of Ca3(PO4)2 containing 0.0100 g L-1? M(Ca3(PO4)2) = 310 g mol-1.
Find [Ba2+] in a saturated solution of BaF2 containing 0.0400 g in 25.0 mL of solution. M(BaF2) = 175.3 g mol-1.
If 2.86 x 10-4 g of Bi(OH)3 are found in 200.0 mL of solution, what is [OH-]? M(Bi(OH)3) = 260.0 g mol-1.
Calculate [Ag+] if 500 mL of Ag2C2O4 contains 0.0205 g of silver oxalate. M(Ag2C2O4) = 303.8 g mol-1.
