Answer:
V = 0.798 L
Explanation:
Hello there!
In this case, for this gas stoichiometry problem, we first need to compute the moles of carbon dioxide via stoichiometry and the molar mass of starting calcium carbonate:

Next, we use the ideal gas equation for computing the volume, by bearing to mind that the STP conditions stand for a pressure of 1 atm and a temperature of 273.15 K:

Best regards!
Answer:
true
Explanation:
in order for the atom to be neutral the number of protons and electrons have to be the same.
Volume of tank =
(given)
Since,
So,

For
:

The significant rule for multiplication, states that the number of significant figures in the answer obtained by multiplication is determined by the value with the lowest number of significant digits.
Since, the minimum number of decimal places in the above multiplication operation is 1 so, the final result must be upto 1 decimal place only.

Hence, volume in
is 243.5.
A=P +N
A=13+14
A=27 this the answer
