Question

what is the molarity of a solution of a phosphoric acid that is made by dissolving 8.00 g of H3PO4 on 0.1 L of water.

A.) 0.0816M

B.) 0.816 M

C.) 0.1 M

D.) 1.6 M

Write the correct molecular equation, complete ionic equation, and net ionic equation, for the reaction that occurs between cobalt(II)chloride and sodium hydroxide

Answer 1

Ans @ what is the molarity of a solution of phosphoric acid ③ 0-816M mass of topoy : 8.0og o volume of wate : 0.12 molas mass of t3p04 : 3+31+4X16 = 98 g/mole * molarity of the solution is defined as the number of moled of solute divided by the volume of the solution in lifted c = n solute (moles) V solution to you & calculate moles of soleate (H2PO4).

* calculate moles of solate (H₂PO4) moles of solute = mass molas mans 8.00g = 0.08163 moles 98 fim de calculate the molarity (C): c = 0. 08163 moles = 0.8163 moled / orlu ã 0-816 M &
