We know the formula of the density:
ρ =
;
So the mass will be equal to:
m = ρ * V = 2.70 * 21.3 = 57,51 g =
57510 mg of substance.
So the answer is 57510.
Answer:
No.
Explanation:
When mass is destroyed, it has to have been transformed into something else. Otherwise that would violate the Law of Conversion of Mass. In this case, the wood converted some of its mass in chemical energy to thermal (or heat) energy.
Hello!
To calculate the
household concentration of NaOH we need to use the
dilution formula, clearing for M2, as you can see in the equation below:
Now, we input the values from the data we have onto this equation. M1=19,1 M; V1=10 mL; V2=400 mL, and solve the equation to get the result:
So, the
household concentration of NaOH will be 0,48 M
Have a nice day!
