1.) Use the information in question 3 to give the patient's creatinine level in ppm.
2.) Creatinine has a molar mass of 113.5 g/mol. What is the molarity of creatinine in the patient'ssample from question 3?
3.) The normal creatinine levels in adults are 0.6-1.2 mg/dL. If a 5.0-mL sample contains 45 μg of creatinine, is that within the normal range? (don't need answer to)
What is the percentage composition of a compound consisting of carbon and hydrogen if 58g of the compound has only 10g of hydrogen.
Treatment of X with Ag(NH3)2 (silver diamine complex), yields a solid Z. When X is treated with H2O/H2SO4, an optically active product W, C7H14O, is formed. Draw the structures of X, Y, Z, and W.
The partial pressure of O2 in air at sea level is 0.21 atm. The solubility of O2 is 1.38E-3 at 1 atm. Use Henry's law to calculate the molar concentration of O2 in the surface water of a mountain lake saturated with air at 20°C and an atmospheric ..
