M(AgNO₃) = 169.9 g; mass.
n(AgNO₃) = m(AgNO₃) ÷ M(AgNO₃).
n(AgNO₃) = 169.9 g ÷ 169.87 g/mol.
n(AgNO₃) = 1 mol; amount of silver nitrate.
c(AgNO₃) = 1 M = 1 mol/L.
V(AgNO₃) = n(AgNO₃) ÷ c(AgNO₃).
V(AgNO₃) = 1 mol ÷ 1 mol/L.
V(AgNO₃) = 1 L.
V(AgNO₃) = 1 L · 1000 mL/L.
V(AgNO₃) = 1000 mL; volume of silver nitrate.
Answer: 2, you divide the value by 1000, so... 2000/1000 = 2.
Answer: Nuclei combine to form a heavier nucleus, releasing energy.
Explanation: e.g two deuterium nucleus (Hydrogen-2 isotopes) forms an He nucleus and energy is released.
