Question

Which equation represents the Ideal Gas Law? (Write in correct letter) A student pours 165 mL of HCl into a beaker. The concentration of the solution is 0.287 M. How many molex of HCl are present? (write in correct letter) (1 L = 1000 mL) 47.4 moles 0.0474 moles 575 moles 1.74 moles List one safety rule applicable to any experiment this semester. Write Avogadro's Number in Scientific Notation. The atmospheric pressure today is 748 mm Hg. Given that 1 atm = 760 mm Hg, convert the pressure to units of atmospheres (atm). Answer to three significant figures. A certain thermometer reads 22 degree C. Convert this to units of Kelvin (K). A certain buret contains 36.5 mL of hydrogen gas. Express this in liters given 1000 mL = 1L

Explanation / Answer

8) pv = nRT is ideal gas law (C) is correct answer

9) Moles = (molarity)(volume in mL) = (0.287)(165) = 47.4 (A) is correct answer

10) Always wear Protective shoes, goggles, gas mask, gloves

11) One mole is equal to 6.02214179 × 1023 electrons, atoms, ions, or molecules, or other elementary units such as molecule

12) 748 X (1/760) = 0.9842 atm

13) 22 + 273 = 295 K

14) 36.5 / 1000 = 0.0365 Liters
