Make up a laboratory solution of 0.10 molar H2SO4 from concentrated (96.0%) H2SO4. You look up the specific gravity of 96.0% H2SO4 and find it is 1.858. Calculate:
a. the weight of 96.0% acid needed per L of solution b. the volume of 96.0% acid used per L of solution c. the density of the 0.1 molar solution
The reaction of water and coal at a high temperature produces a mixture of hydrogen and carbon monoxide gases. This mixture is known as synthesis gas (or syngas). What mass of hydrogen gas can be formed from the reaction of 51.3 g of carbon with e..
Determines the mass of an unknown gas to be .43 grams at 37 C as well as 720 mm Hg in a 250 mL container. Explain what is the molecular mass of the unknown gas. Use n=(PV/RT) but a little confused on where to proceed.
Benzyl ethyl ether reacts with concentrated aqueous HI to form two initial organic products (A and B).
if 100 mL of 0.800 M Na2SO4 is added to 200 mL of 1.20 M NaCl, what is the concentration of Na ions in the final solution?
Calculate the value of q, w, delta E , for the reversible isothermal expansion at 300k of 2.00 mol of a perfect gas
To obtain the same antifreeze protection requires 76g of propylene glycol to replace each 62g of ethylene glycol. Calculate the mass of propylene glycol required to replace 7.00gal of ethylene glycol. The density of ethylene glycol is 1.12 .
