<prompt> Unapewa seti ya elementi za kemikali. Andika programu ambayo husawazisha jumla ya MAsses zote.H, He, Li, Be, B, C, N, O, F, Ne, Na, Mg, Al, Si, P, S, Cl, Ar  <response>: Here is a program written in Python that calculates the sum of masses for the given chemical elements:pythonfrom mendeleev import elementdef sum_of_masseselements: total_mass 0 for e in elements: total_mass elemente.atomic_weight return total_masselements H, He, Li, Be, B, C, N, O, F, Ne, Na, Mg, Al, Si, P, S, Cl, Arresult sum_of_masseselementsprintThe total mass of the given elements is:, result In this program, we use the mendeleev module, which contains the information of the elements in the periodic table. We define a function, sum_of_masses, which takes a list of elements as an argument. Inside the function, we iterate through each element and add its atomic weight to a variable, total_mass, using the atomic_weight attribute of the element object from the mendeleev module. Finally, the function returns the total_mass variable. We then call this function with the input list of elements and print the result, which gives us the sum of masses for the given elements.
