小熙同学利用下列器材：天平(无砝码)、两只完全相同的小烧杯、量筒、水、滴管、细线完成了小石块密度的测量.水的密度为1.0×103kg/m3.操作步骤如下：

(1)把天平放在水平桌面上，将_____移到标尺的零刻度线处，调节平衡螺母，使天平平衡;

(2)先把两只完全相同的小烧杯分别放在天平左右两盘上，再把小石块放入左盘烧杯中;

(3)向量筒中倒入适量的水，液面如图2所示，则量筒中水的体积为_____cm3;

(4)现将量筒中的水倒一部分至右盘小烧杯中，再利用滴灌来调节量筒与烧杯中水的体积，当天平再次平衡时量筒内剩余水的体积如图3所示，则小石块的质量m石=_____g;

(5)用细线拴好小石块，慢慢放入量筒中直到完全浸没，液面的示数如图4所示，则小石块的体积V石=_____cm3，小石块的密度ρ石=_____

kg/m3.
