Blood pressure 121/76 - what does it mean? Your blood pressure reading of 121/76 indicates a Normal blood pressure. The requirements are met with a systolic (upper) value under 130 mmHg and a diastolic (lower) value of under 85 mmHg. The normal blood pressure is a good requirement to avoid damaging of vessels and organs.

Antimony has two naturally occurring isotopes and its average atomic mass is 121.76 amu. The mass of antimony-121 is 120.904 amu and the mass of antimony-123 is 122.904 amu. Using the average mass from the periodic table, find the % abundance of antimony-121. Write your final answer in three decimal places and do not write the % sign.

In a sample of 100 Sb atoms, what is the probability that a single selected atom has a mass of 121.76 amu? E) Not possible to determine. The atomic mass is an average that represents the abundance of each isotope. No individual atom has this mass. The element antimony (Sb) has an atomic mass of 121.76 amu.

2024年4月24日 · 屏幕尺寸是长121.76厘米，宽68.49厘米。 我们平常所说的电视机多少英寸（简称“寸”）指的是屏幕的对角线长度，与宽高比无关。 大尺寸电视机（显示器）基本上都是长宽比为16：9的屏幕。 55英寸，是英制单位，换算成公制单位是：2.54×55＝139.7（厘米），这是屏幕对角线的长度。 55英寸，是英制单位，换算成公制单位是：2.54×55＝139.7（厘米），设屏幕的长是x厘米，宽就是9x/16厘米。 …

In a sample of 100 Sb atoms, what is the probability that a single selected atom has a mass of 121.76 amu? How many neutrons are in an atom of uranium-235? Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on. Question: The element antimony (Sb) has an atomic mass of 121.76 amu.

From the atomic weight of Sb = 121.76 one can conclude that: antimony-123 has the highest percent natural abundance O most antimony atoms have a mass of 121.76 amu O antimony-121 has the highest percent natural abundance O both. There are 2 steps to solve this one.

2016年11月23日 · As given in the problem the atomic weight of antimony is 121.76 amu. two naturally occurring isotopes of antimony. 121-Sb has an isotopic mass of 120.9038 amu and a **natural **abundance of 57.40%. The atomic mass of the **antimony **= natural **abundance **×atomic mass of the isotope. 121.76 = 0.574×120.9038 + 0.426 × (isotopic mass of 123-Sb)

1、坐标拾取：点击地图上任意一点，即可获取地图上该点的坐标（维度、经度）。 2、经纬度定位：根据已有的维度坐标、经度坐标定位到具体位置，只需输入已知的维度、经度，即可查询到具体位置并且会在地图上标注出来。 3、查询经纬度：输入你的具体地址（建议详细到省、市、县、区、街道），即可查询到具体的维度和经度。 备注：这里使用的是GCJ-02坐标系地图（腾讯地图和高德地图都通用），如果你使用的不是GCJ-02坐标系地图，而是使用的是谷歌地图、百度地 …
