（6分）市场出售的某种品牌食品用发酵粉，实际上是由小苏打与一种有机酸式盐（不含结晶水）等物质的量混合物而成。

取一定量发酵粉溶于足量水中，两种酸式盐恰好完全反应，生成标准状况下的二氧化碳气体4.48L，将溶液蒸干并干燥，得到一种正盐R，其质量为42g。对此正盐进行下列实验：①用洁净的铂丝蘸取少许R，在无色火焰上灼烧，火焰呈黄色，再通过蓝色钴玻璃又见到紫色火焰；②经过元素分析仪测定，R中的碳、氢、氧的质量分数分别为22.86%、1.90%、45.71%；③光谱分析可知R中含有性质一样的两个羟基，且不含亚甲基（CH₂）。

试回答下列问题(写出简要推导过程)：

⑴正盐R中所含的金属元素是____________，R的物质的量为__________。

⑵发酵粉中有机酸式盐的结构简式为______________________________。

The popular song ‘Gangnam Style’ from South Korean recording artist PSY has just become the most watched video on YouTube ever, getting more than 808 million views on the popular media site.

The distinction was previously held by another pop heavyweight, Justin Bieber, whose song ‘Baby’ had a little more than 804 million views at press time. PSY made the announcement on his Twitter page earlier today.

Since its release, the song has defeated such other popular videos as Jennifer Lopez’s ‘On the Floor’ and Eminem's ‘Love the Way You Lie’. And in September, 'Gangnam Style' also became the most liked video on YouTube, now with nearly 5.4 million thumbs up.

At the time of the announcement, the Guinness Book of World Records released a statement saying: “In years past it was unthinkable that something would be viewed a hundred million times, and now Gangnam Style has achieved more than twice this figure in just three months on YouTube. PSY, your certificate is waiting here at our office, come pick it up any time!”

Despite its massive popularity, the video shows no signs of slowing down, and it even has a shot at becoming the first video to get more than one billion views.

If it maintains its current rate of around six million new views per day, ‘Gangnam Style’ would be in line to break that record by the end of the year.

The YouTube honors are just the latest in a long list that shows just how popular the song has become. Since it was released in July, the song has seen a meteoric rise through the music industry.

It has found its way to the tops of music charts in more than 30 countries, including the United Kingdom, Germany, France, Spain and Canada, while providing material for thousands of parody（恶搞）videos.

It became part of the 2012 presidential elections with the now famous ‘Mitt Romney Style’ video and was even used by the North Korean government in propaganda films promoting their supreme leader.

Meanwhile, such influential figures as President Obama, UN Secretary General Ban Ki-moon and Google Executive Chairman Eric Schmidt have all made mention of the hit song.
