Explanation:
we know that 0.250 L = 0.250 dm3
molarity = concentration in dm3/ volume
molarity = 0.175/0.250 = 0.7 mol/dm3
Answer:
false; the purpose of antibiotics is to kill bacteria
Explanation:
Answer: Heat of the solution = mass water × specific heat water × change in temperature
mass water = 260ml (1.00g/ml ) = 260g
specific heat of water = c(water) = 4.184J/ g°C
Heat change of water = final temperature - initial temperature
= 26.5 - 21.2
= 5.3 °C
H = 260 g ( 4.184J/g°C ) (5.3°C) = 5765J
Molar heat = ![\frac{5765J}{0.350mol}](https://tex.z-dn.net/?f=%5Cfrac%7B5765J%7D%7B0.350mol%7D)
= 16473J/mol
Explanation: finding molar heat requires first to look at specific heat of water and the change of water temperature
