请教下这句话什么意思?In a typical synthesis, 2 mmol of the alkaline earth metal (274.7 mg of Ba or 175.2 mg of Sr) was stirred in a vial with 25 mL of benzyl alcohol at slightly elevated temperature until completely dissolved. For the (Ba,Sr)TiO3, 1 mmol of Ba and 1 mmol of Sr were dissolved together in the benzyl alcohol. Next, 1 mol equivalent of Ti(OiPr)4 was added dropwise to the solution. 这里加入1mol当量难道真的是要加入1mol的量?还是和之前2mmol保持摩尔比为 1的意思?查看更多7个回答 . 30人已关注
