    21,200g/mol

    Explanation:

    General formula of polyethylene molecule is (C2H4) n

    n = 750

    Therefore, Formula of polyethylene molecule is (C2H4) 750 = C1500H3000

    Molecular weight = (1500*12.1 + 3000*1) g/mol = 18,150 + 3,000 = 21,150 = 21,200g/mol (to three significant figures)
