another option would be dbms_xmlgen.getxml:
create table master (
    table_name varchar2(30)
  , column_name varchar2(30)
insert into master (table_name, column_name) values ('EMP', 'EMPNO');
insert into master (table_name, column_name) values ('EMP', 'DEPTNO');
insert into master (table_name, column_name) values ('EMP', 'COMM');
select dba_tab_cols.owner
     , dba_tab_cols.table_name
     , dba_tab_cols.column_name
     , to_number(
          extractvalue(
                    xmltype(
                            dbms_xmlgen.getxml('select count(*) c from '
                                                || dba_tab_cols. owner
                                                || '.'
                                                || dba_tab_cols.table_name
                                                || ' where '
                                                || dba_tab_cols.column_name
                                                || ' is null')
                    ,'/ROWSET/ROW/C')) num_nulls
  from dba_tab_cols
  join master
    on (     dba_tab_cols.table_name = master.table_name
         and dba_tab_cols.column_name = master.column_name )
where dba_tab_cols.owner = 'SCOTT'
OWNER      TABLE_NAME    COLUMN_NAME     NUM_NULLS
SCOTT      EMP           EMPNO                   0
SCOTT      EMP           DEPTNO                  0
SCOTT      EMP           COMM                   10
