What is the mass of 1 carbon atom??? |
|
Answer» Answer: ATOMIC MASS, the quantity of MATTER contained in an atom of an element. It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, 1.992646547 × 10−23 gram, which is assigned an atomic mass of 12 UNITS. In this scale 1 atomic mass unit (amu) corresponds to 1.660539040 × 10−24 gram.Explanation: The mass of a single atom of carbon 12 is simply the mass of a mole of the stuff 12garms divided by Avogadro's NUMBER (6.022×1023). that works out of 1.9927×10-23 grams.Mass of one mole of C12 = 12 g. so mass of 1 atom of C12 = 1.9927e-23 g. Now, C12 has mass of 12 amu.Hope this Answer Helps you to Gain Knowledge |

They are grouped into various groups like Bacteria, fungi, algae, protozoa and viruses. Many of these organisms are useful to human and nature while some are harmful and even cause diseases. Type Useful microorganisms Harmful microorganisms Bacteria Lactobacillus (curd bacteria) Salmonella typhi (causes typhoid) Fungi Penicillium notatum (to make antibiotics) Trichophyton rubrum (Athlete's foot) Algae Anabaena (biological nitrogen fixation) blue-green algae and red tides (produce toxins) Protozoa Paramecium (kills harmful bacteria) Plasmodium (malaria fever) Virus polio, chicken pox (to make VACCINES) HIV (causes AIDS) Harmful effects of microorganisms: Bacteria: Causes various diseases such as typhoid, diarrhea, and cholera. Fungi: Causes a large number of diseases in plants and in ANIMALS such as rust diseases in plants, fruit rot in apple, red rot in sugar cane and RING worm disease in human beings. Algae: Algal boom in water (rapid growth of algae) causes poisonous effect after they die, which in turn results in the death of aquatic organisms. Protozoa: Causes Amoebic dysentery, pyorrhoea and SLEEPING sickness etc. Virus: Cause small fox, common COLD, influenza, herpes, hepatitis, polio and rabies.
