  INTERNATIONAL SPACE STATION(ISS) PC - NASA Five space agencies including NASA, JAXA, ROSCOSMOS, CSA, ESA have contributed to the space station assembly. The International Space Station is larger than a six-bedroom house with six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window. In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets. Peggy Whitson  set the U.S. record for spending the most total time living and working in space at 665 days on Sept. 2, 2017. To mitigate the loss of muscle and bone mass in the human body in microgravity, the astronauts work out at least two hours a day. The solar array wingspan (356 feet, 109 meters) is longer than the world’s largest passenger aircraft, the Airbus A380 (262 feet, 80 meters). pc-NASA The space station is 356 feet (109 meters) end-to-end, one yard shy of the full length of an American football field including the end zones. A spacecraft can arrive at the s...

Class 12th "Solution" Chapter no. 02

Molarity : It is a solution which is the number of moles of the solute present in per liter of solution.  (प्रति लीटर विलयन में घुलित विलेय पदार्थ के मोलों की संख्या को विलयन की मोलरता कहते हैं)।  यह किसी निश्चित ताप पर ही हो सकता है।  •  It is denoted by 'M'. Formula :   •    M = (number of moles of solute/volume of solution in liter)                          Or                     M = n/v Unit : mol/liter or mol/L       Formality : It is used to solve the concentration of ionic compounds solutions. Denoted by 'F'. We could use  gram formula mass for ionic compounds. Because they have no discrete molecules e.g. molecular mass word is not valid for that kind of compounds.  "किसी निश्चित ताप पर प्रति लीटर विलयन में घुलित आयनिक पदार्थ के ग्राम सूत्र द्रव्यमान की संख्या विलयन की उस ताप पर फॉर्मलता कहलाती है।" (Gram ...
