Density=mass/volume so mass= volume*density
Volume=40*20*9
Mass=7200*2.75
=19800
Now turn it into kg which will be
19800\1000
=19.8
Answer:
2HCL
Explanation:
Both the elements have 2 so when placing the 2 infront ,it'll distribute/ apply to both
Homeostasis helps organisms Maintain balance
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the% m / m concentration of that solution is 6.66%.
