Answer:
36% m/v
Explanation:
An antibiotic solution must be prepared by diluting 100. mL of a 90. % m/v solution and bringing up the volume to 250 mL. What is the concentration of the resulting solution?
the new solution is 100/250 X 90% m/v = 36% m/v
Answer:
11.29 kJ (to 4 sf)
Explanation:
Here, ammonia is the limiting reactant.
For the reaction to occur once, 4 moles of ammonia must be consumed.
Thus means that the reaction can occur 0.1579/4=0.039475 times.
Therefore, (286)(0.039475) = 11.29 kJ (to 4 sf)
