- CM (đường)=\(\dfrac{n}{V}\) = 1/2=0,5M
- đổi 1500ml =1,5l
CM(CuSO4) =\(\dfrac{nCuSO4}{V\text{dd}CuSO4}=\dfrac{0,6}{1,5}=0,4M\)
- đổi 5000ml=0,5l
n NaCl=11,7/58,5=0,2mol
CM(NaCl)=0,2/5=0,04M
\(C_{M_{ddđường}}=\dfrac{1}{2}=0,5\left(M\right)\)
\(C_{M_{CuSO_4}}=\dfrac{0,6}{1,5}=0,4\left(M\right)\)
\(n_{NaCl}=\dfrac{11,7}{58,5}=0,2\left(mol\right)\)
\(\Rightarrow C_{M_{NaCl}}=\dfrac{0,2}{5}=0,04\left(M\right)\)
