Suppose 25.4 grams of NaCl was added to 400 mL of water. The resulting solution was again diluted with water 1:100 with water. What is the final concentration of the NaCl in μM? The molecular weight of NaCl is 58.44.
A flask weighs 64.25 g when empty and weighs 91.75 g when filled with water at 20oC. However, when the flask is filled withthe same volume ofisopropyl alcohol at the same temperature, the combinedmass of flask and alcohol is 86.00 g. (a) If the density of water is 0.99823 g/mL at 20oC, what is the volume of water that filled the flask? (b) Determine the density of isopropyl alcohol at 20oC.
A Solution is formed when two or more substances combine to yield a mixture that is homogeneous at the molecular level. Is a container filled with water (H,O) and some beach sand (SiO2) a solution? O Yes, because SIO, dissolves completely in water to form Si(aq) and O (aq) solvated ions. O No, because water is not capable of forming homogeneous solutions. O No, because SiO, is a nonpolar covalent molecule that does not dissolve completely in water to form solvated ions. O Yes, because water reacts violently with beach sand to form H2SIO3, Metasilicic Acid, a diprotic strong acid.
A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 11.10 g.L-¹. The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 4.30 g⋅L¯¹. Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate the percentage of Lake Parsons which has evaporated since it became isolated. Be sure your answer has the correct number of significant digits.

40 X x 2008 xample 8. The laboratory reagent, concentrated nitric acid, is generally 69 per cent by mass of nitric acid (HNO3). Calculate volume of this solution which contains 19.9 g of HNO3 (density of concentrated nitric acid solution is 1.41 g cm -3). If th I of II
The thermal conductivities of human tissues vary greatly. Fat and skin have conductivities of about 0.20 W/m · K and 0.020 W/m · K respectively, while other tissues inside the body have conductivities of about 0.50 W/m · K. Assume that between the core region of the body and the skin surface lies a skin layer of 1.0 mm, fat layer of 0.50 cm, and 3.2 cm of other tissues. (a) Find the R-factor for each of these layers, and the equivalent R-factor for all layers taken together, retaining two digits. Rskin m2 · K/W Rfat m2 · K/W Rtissue m2 · K/W R m2 · K/W (b) Find the rate of energy loss when the core temperature is 37°C and the exterior temperature is 0°C. Assume that both a protective layer of clothing and an insulating layer of unmoving air are absent, and a body area of 2.0 m2. W

The world population is estimated to be 7.4 x 109. Nauru is the smallest island nation and comprises 1.5 x 10-4% of the world population. If the percentage of left-handed people is approximately 12%, estimate the number of left-handers on the island of Nauru.
A 15000 L tailings pond at a mine site was analyzed for cadmium contamination. First, a 25.0 mL sample of water was removed from the pond. Then the solution was evaporated to dryness, and 56.1 mg of cadmium was recovered (the identity of the metal was confirmed through other methods). Assuming the water is homogeneously distributed throughout the pond, what is the concentration of cadmium in the tailings pond?
