Answer:

Mass of copper metal will be 2.06756 gram

Explanation:

We have given number of moles of copper n = 0.03256

Molar mass of copper = 63.5 u

We have to calculate mass of copper metals in gram

We know that number of moles is given by number\ of\ moles=\frac{mass\ in\ gram}{molar\ mass}

0.03256=\frac{mass\ in\ gram}{63.5}

Mass in gram = 2.06756 gram

So mass of copper metal will be 2.06756 gram

First, get about 20 mL of the quinine stock solution in a clean beaker to prepare 250 mL of about 2 ppm quinine in 0.05 M H2SO4.
iris [78.8K]

Answer:

Volume of acid, Va=250mL; Volume of quinine,Vb=20mL; Molarity of acid, Ma=0.05M.

Molar mass of acid= H2+S+O4= 2+32+(16X4)= 2+32+64=98g

Concentration of acid, Ca= Molar mass of acid/ Ma =98/0.05=1960g/mol

Explanation: To calculate concentration of quinine, Cb is as follow

Va*Ca=Vb*Cb

∴ Cb=Va*Ca/Vb =250*1960/20 =24500g/mol
