The mass of beryllium that combines with 1.000 g of oxygen to form beryllium oxide is 0.5633 g. When atomic masses were first being measured, it was thought that the formula of beryllium oxide was Be2O3. What would be the atomic mass of beryllium if this were the case? Assume that oxygen has an atomic mass of 16.00.

翻译如下:
大量的铍相结合,与1.000克氧,形成氧化铍是0.5633 g.当原子群众首先被衡量的,据认为,公式氧化铍是be2o3 。什么将成为原子质量铍如果是这样的情况呢?假设有一个氧原子质量的16.00 。

很简单。他告诉你,在三氧化二铍中,有0.5633g铍,1g的氧,又告诉你了氧是16,问Be的原子量。假设Be为X,2X:3*16=0.5633:1.自己算一算吧。

与1.000克氧结合成氧化铍的铍的质量为0.5633克。
氧化铍公式是be2o3 ,求铍相对原子质量。

铍相对原子质量为9.
