Astudent synthesized a nickel (ii) ammonia complex with a molecular formula of [ni(nh3)x(h2o)y]clz. the amount of ammonia in the complex was analyzed using 0.2005m hcl. the student determined that the reaction required 20.02ml of hcl to react with 0.1550g of the nickel(ii) ammonia complex. answer the following questions. atomic masses: ni = 58.69g/mol; h= 1.00g/mol; o= 16.00g/mol; cl = 35.45g/mol; n= 14.00g/mol(a) determine the value for "z" in the compound. briefly explain your reasoning. hint: the complex salt must be electrically neutral (i. e. no net charge)(b) calculate the experimental equivalent weigth for the nickel(ii) ammonia complex (i. e. grams of complex per mole of ) based on the results from (a) and (b), propose a molecular formula for the neutral nickel(ii) ammonia coordination complex. show all your work. hint: x+y≤6. try different combinations of "x" and "y" to see which combination best matches the calculated experimental equivalent weight.
