A student placed 12.0 g of glucose (rm C_6H_{12}O_6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100.-rm mL mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 60.0-rm mL sample of this glucose solution was diluted to 0.500 rm L. How many grams of glucose are in 100. rm mL of the final solution?
A 0.479 g sample of nitrogen, oxygen or neon gas occupies a volume of 265 mL at 157 kPa and 20?C. What is the molar mass and identity of the gas
Whats the reduced mass of CO2. I know how to do it for CO but since its 3 molecules do you go m1+m2+m3/m1m2m3 or is m2 just 32
After 273 m3 of ethylene oxide at 748 kPa and 525 K is cooled to 293 K, it is allowed to expand to 1.10 × 103 m3. What is the new pressure?
Calculate deltaG at 298K if the reaction mixture consists of 7.4 atm of H2, 0.056 atm of P4, and 0.29 atm of PH3. Reaction is 6H2(g)+P4(g)-->4PH3(g).
If a gas held at constant pressure had an initial volume of 5.00 L and the temperature changed from 35°C to 578 K what would be the final volume of this gas?
What formula is used to find the work needed to compress water from atmospheric pressure to a higher pressure (with ambient Temperature)? I know about w = integral (-PdV), but V is constant. What is this formula in terms of delta-P
Calculate the molar mass of the unknown. Assume that the molal freezing point depression constant of water is 1.86°C•kg/mol and that the freezing point of water is 0.00°C. Please show all calculations in solving the problem
If you had a mixture of NaCl and Na2CO3, would the action of concentrated H2SO4 enable you to decide whether both Chloride ions and carbonate ions were present
