Explanation:
From the parameters given here in this question;
n= 1.46 moles
P= 0.982 miles
T= 13°C + 273 = 286 K
R= 0.0821 L.atm/mol.K
We are to find the volume using the ideal gas equation which states that;
PV=nRT
V= nRT/P
V= 1.46 × 0.0821 × 286/0.982
V= 34.9 L
b) Boyle's law can be proven from the kinetic theory of gases. Boyle's law states the relationship between the volume and pressure of an ideal gas. Boyle's law states that the pressure of a given mass of ideal gas is inversely proportional to it's volume at constant temperature and pressure. This is the only correct statement among the options listed in the question.
Answer:
6
Explanation:

Answer: 40.1%
Explanation: The mass of calcium in this compound is equal to 40.1 grams because there's one atom of calcium present and calcium has an atomic mass of 40.1 . The molar mass of the compound is 100.1 grams. Using the handy equation above, we get: Mass percent = 40.1 g Ca⁄100.1 g CaCO3 × 100% = 40.1% Ca.
