题目

某学生提供的实验数据如下，其中肯定错误的是（ ）①用100毫升的量筒量取67.60mL的液体②用托盘天平称取22.5gKCl③酸碱中和滴定时，消耗0.1000 mol/L的盐酸23.25 mL④用广泛pH试纸测得某溶液的pH＝4.4A. ①② B. ②③ C. ③④ D. ①④ 答案：【答案】D【解析】①由于量筒的最小读数为0.1mL，所以无法用100毫升的量筒量取67.60mL的液体，故①错误；②托盘天平的最小读数可以为0.1g，可用托盘天平称取22.5g KCl，故②正确；③酸式滴定管和碱式滴定管的最小读数为0.01mL，所以酸碱中和滴定时，消耗0.100 0mol•L-1的盐酸的体积可以为23.25mL，故③正确-- Have all the students known that our class will visit the factory this afternoon? -- Yes. Every student _________ about it. [　　] A. tellsB. toldC. was toldD. has told
