1.小明测量植物油密度时,按下列顺序进行了操作:①用天平称出空烧杯的质量 m_1;②向烧杯中倒入适量植物油,测出烧杯与植物油的总质量 m_2;③将烧杯中植物油倒入量筒中,测出植物油的体积v;④计算出植物油的密度ρ。(1)请根据上述实验,设计记录数据表格;(2)图1显示了小明按上述操作完成实验时得
1. Xiao Ming measures the density of vegetable oil, and operates in the following order: 1 The mass of the empty beaker is weighed using the balance m_1; 2 Pour the appropriate amount of vegetable oil into the beaker, measure the total mass of the beaker and vegetable oil m_2; 3 Place the vegetable oil in the beaker Pour into the measuring cylinder and measure the volume v of the vegetable oil; 4 Calculate the density ρ of the vegetable oil. (1) According to the above experiment, design the record data table; (2) Figure 1 shows that Xiao Ming can finish the experiment according to the above operation.
