The correct answer is: (b) 35.5 u The atomic mass of chlorine is approximately 35.5 u, which is the weighted average of the isotopes chlorine-35 and chlorine-37. This average accounts for their relative abundance in nature. Class 9th Science NCERT ...
(d) valency of each element. The chemical formula of a molecular compound is determined by the valency of each element. The valency indicates how many bonds an element can form, which helps in combining elements in the correct ratio to ...
Linear Programming is a mathematical method used to optimize a linear objective function subject to linear constraints. It helps in making the best decision by determining the optimal values for variables. The solution is found within the feasible region formed ...
To find the number of neutrons in sodium (Na) and magnesium (Mg), we subtract the atomic number from the atomic mass: Sodium (Na) has an atomic number of 11 and an atomic mass of 23. Neutrons = 23 – 11 ...
