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)

Carbon dioxide is an essential component of atmosphere. However, when the concentration of CO_2 increases in the atmosphere, it can lead to global warming through green house effect. Similarly, rain water is an essential source of water. It has pH of 5.6 due to the formation of H^+ ions from the reaction of rain water with CO_2 present in the atmosphere. When pH of the rain water falls below 5.6 due to the presence of acids in the atmosphere, it has very damaging effects. What is PAN?

Enzymes convert glucose (M = 180.2) to ethanol (M= 46.1) according to the equation C_(6)H_(12)O_(6) rArr 2C_(2)H_(5)OH + 2CO_(2) What is the maximum mass of ethanol that can be made from 15.5kg of glucose?

Converting molality to molarity: Ethylene glycol, C_(2)H_(4)(OH)_(2) is a colourless liquid used as an automobile antifreeze. If the density at 20^(@)C of a 4.500 m solution of ethylene glycon in water is 1.279 g mL^(-1) , what is the molarity of the solution? The molar mass of ethylene giycon is 62.00 g mol^(-1) . Strategy: A 4.500 m solution of ethylene glycol water contains 4.500 mol of glycol in every one kilogram of water. To find the solution's molarity, we must find the number of moles of solute per litre of solution. We can find volume fome the mass the mass of the solution by using density as a conversion factor. So we cam take the mass of solution that contains 1 kg of H_(2)O and use the density to convert this quantity of solution to volume.

Units of parts per million (ppm) or per billion (ppb) are often used to describe the concentrations of solutes in very dilute solutions. The units are defined as the number of grams of solution per million or per billion gram of solvent. Bay of Bengal has 2.1 ppm of lithium ions. What is the molality of Li^(+) in this water ? (Li = 7)

A vessel with a symmetrical hole in its bottom is Paste on a cart. The mass of the vessel and the cart is 1.5 kg . With what force F (in xx 10^(2)N) should the cart be pulled that the maximum amount of water remains in the vessel. The dimensions of the vessel are as shown in the figure. Given that b = 50 cm, c = 10 cm , area of base A= 40cm^(2), L = 20 cm, g = 10 m//s^(2).

Equivalent Mass The eqivalent mass of a substance is defined as the number of parts by mass of it which combine with or displace 1.0078 parts by mass of hydrogen, 8 parts by mass of oxygen and 35.5 parts by mass of chlorine. The equivalent mass of a substance expressed in grams is called gram equivalent mass. The equivalent mass of a substance is not constant. It depends upon the reaction in which the substance is participating. A compound may have different equivalent mass in different chemical reactions and under different experimental conditions. (a) Equivalent mass of an acid It is the mass of an acid in grams which contains 1.0078 g of replaceable H^(+) ions or it is mass of acid which contains one mole of replaceable H^(+) ions. It may be calculated as : Equivalent mass of acid= ("Molecular mass of acid")/("Basicityof acid ") Basicity of acid = Number of replaceable hydrogen atoms present in one molecule of acid (b) Equivalent mass of a base It is the mass of the base which contains one mole of replaceable OH^(-) ions in molecules. Equivalent mass of base= ("Molecular mass of acid ")/("Acidity of acid") Acidity of base= Number of replaceable OH^(-) ions present in one molecule of the base Equivalent mass of an oxidising agent (a) Electron concept: Equivalent mass of oxidising agent = ("Molecular mass of oxidising agent")/("Number of electrons gained by one molecule") (b) Oxidation number concept: Equivalent mass of oxidising agent= ("Molecular mass of oxidising agent")/("Total change in oxidation number per molecule of oxidising agent") When NO_(2) is dissolved in water solution become acidic. Equivalent weight of NO_(2) in this reaction (NO_(2)+H_(2)O to HNO_(3)+HNO_(2)) is :
