Answer: 0.125moles
Explanation:
From the question above, we are only given the values of the volume and molar concentration of CuSO4 solution.
Volume of CuSO4 solution = 250mL= 250/1000L = 0.25L
Molar concentration of CuSO4 solution= 0.50M
Number of moles of CuSO4= Molar concentration of CuSO4 × volume of CuSO4
Number of moles of CuSO4= 0.50mol/dm^3 × 0.25L
Number of moles of CuSO4= 0.125moles
Therefore 0.125moles of CuSO4 are used to make 250 mL of a 0.50M CuSO4 solution.
Chlorine is diatomic so the gas is Cl2. Add the molar mass *2 and that is the grams per mole
The atomic number is the amount of protons in a nucleus, while the mass number is the protons plus neutrons.
Atomic number: 8
Atomic mass : 8+8 = 16
Answer: Atomic mass is 16, while atomic number is 8
The answer is A hope that help
