(ii) Calculate the number of molecules of sulphur (S8) present in 128gm of sulphur.(atomic mass of Sulphur is32gm). |
|
Answer» The MOLECULES formula of sulphur is given to be S8 ( it Contains 8 atoms of sulphur ). So , the molecular mass of sulphur molecule is 32 × 8 = 256 U. This means that 1 MOLE of sulphur molecules is equal to 256 GRAMS. Now, 256 g of sulphur = 1 mole of sulphur moleculesSo, 16 g of sulphur = 1/ 256 × 16 mole of sulphur molecules = 0.0625 mole of sulphur molecules Also, 1 mole of sulphur molecules = 6.023 × 10²³ molecules So, 0.0625 mole of sulphur molecules = 6.025 × 10²³ × 0.0625 molecules= 3.76 × 10²² molecules |

What is the location of a Bicuspid valve |
|
Answer» Bicuspid aortic valve (BAV) is an INHERITED form of heart disease in which two of the leaflets of the aortic valve fuse during development in the womb resulting in a two-leaflet valve (bicuspid valve) instead of the normal three-leaflet valve (tricuspid). BAV is the most common cause of heart disease present at birth and affects approximately 1.3% of ADULTS. Normally, the mitral valve is the only bicuspid valve and this is situated between the heart's left ATRIUM and left ventricle. Heart valves play a crucial role in ensuring the UNIDIRECTIONAL FLOW of blood from the atrium to the ventricles, or from the ventricle to the aorta or pulmonary trunk. |
