Weighing 3104 carats (1 carat=200mg), the Cullinan diamond was the largest natural diamond ever found. How many carbain atoms were present in the stone?

Text Solution

Verified by Experts

Mass of the stone
=3104`xx`200=620800mg=620.8g .
Number of atoms of carbon
`=("Mass in gram")/("Gram-atomic mass")xx6.023xx10^(23)` ltbr. `=(620.8)/(12)xx6.023xx10^(23)=3.12xx10^(25)`

The mercury content of a stream was believed to be above the minimum considered safe limit (1 part per billion, by mass). An analysis indicated that the concentration was 1.68 parts per billion. How many Hg atoms are present in 15 L of water, the density of which is 0.998 g/ml. (Hg = 200)

Read the passage and answer the following questions. Mendeleev was a Russian chemist, who contributed the most for the development of periodic table of elements wherein the elements were arranged on the basis of their fundamental property, the atomic mass and also on the similarity of chemical properties. Only 63 elements were known at his time. He arranged the 63 elements in the increasing order of the.ir atomic masses and found that there was a periodic recurrence of elements with similar physical and chemical properties. He observed that elements with similar properties fall in the same vertical column. These vertical columns are called groups and horizontal rows of elements are called periods. Mendeleev predicted the existence of certain elements not known at that time and named two of them as Eka-silicon and Eka-aluminium. How many valence electrons are present in each one of them?

Agrabah never sleeps peacefully! A robbery has taken place at Agrabah's palace the previous night and one of the most precious treasures, a rare diamond is missing. Information received from the sources has pointed out that Essos, an allied nation is behind this robbery. Aladdin and Genie left for Essos as soon as they heard the news. On reaching there they find out that the diamond is guarded by a two-level cage, each having 9 sections. The guards placed there have to occupy 16 sections, 8 on the upper level and 8 on the lower. (The two central sections are set aside for storing weapons). There are 4 conditions for placing guards: 1. All 16 sections must be occupied. 2. No section can hold more than 3 guards. 3. Each of the four outer sides (total of both levels) must hold 11 guards. 4. The whole upper level must hold twice as many guards as the whole lower level. Although the cage facility received 3 fewer guards than expected. The facility placed the guards in conformity with these four conditions. The Aladdin asked Genie to bring back the diamond but in order to do so, Genie needs some information. He needs to find out how many guards were expected?
