Now let's see how to make 1 N and 1M H2SO4 from 98% concentrated H2SO4 . This calculation varies with concentration of H2SO4. Because density varies with concentration of H2SO4 . Now we are having density 1.84 for 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then first find out density of it then put that value in below formula instead of 1.84 H2SO4 is liquid, so at first we need to convert H2SO4 molecular weight (gm) into volume (ml) let's use formula density = mass / volume volume = mass of HCl / density 98.08 / 1.84 V = 53.30 ml Here we are making 1M and 1N H2SO4 from 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then use that percentage value in below formula rather than 98%. Let's use formula 1M H2SO4 (98%) = 53.30 ml [ V ] 100% ...
Vitamins are micronutrients which help perform important functions in our body. The most essential vitamins needed by our body are vitamin A, C, D, E, K and a group of B-complex vitamins. Vitamin A is required to make a pigment called Rhodopsin in our eyes. Rhodopsin helps us to see in low light conditions. Thus, without vitamin A, rhodopsin won't be produced, causing night-blindness. Source of vitamin A : yellow, red and green (leafy) vegetables, such as spinach, carrots, sweet potatoes and red peppers. yellow fruit, such as mango, papaya and apricots. Vitamin C and E are antioxidants. Unstable free radicals damage our cell's DNA, leading to illness or cancer. Vitamin C and E neutralize the free radicals, preventing cell damage. Source of vitamin C and E : Citrus Fruits. Raw citrus fruits are very high in vitamin C.... • Broccoli.... • Red Cabbage.... • Kiwi.... • Bell Peppers. Vitamin D helps our body to absorb calcium to build strong bones. Thus, lack of vitamin D can ...
