小明同学在做“用天平和量筒测盐水密度”的实验。请完成以下实验要求．

①用天平称出空烧杯的质量m₁=63g；

②往空烧杯中加入适量盐水，用天平称烧坏和盐水的总质量，天平平衡后，右盘中砝码的总质量是140g，游码位置如图甲所示，则盐水和烧杯的总质量m₂=____ g；

③把烧杯中的盐水全部倒入量筒中，如图乙所示，则盐水的体积V=____ cm³；

④测出的盐水密度ρ=____ 　kg/m³；

⑤通过上面实验测出的盐水密度是偏大还是偏小？____ ；

⑥若天平的砝码被磨损了，用这样的天平称物体的质量，则测量值偏____ 。

根据短文判断下列句子是否正确,正确的写 “正确”,错误的写 “错误”
