Answer:
15.4 mol CO₂
Explanation:
5.12 mol C₃H₈ × (3 mol CO₂ / mol C₃H₈) ≈ 15.4 mol CO₂
The answer is A the heat is removed because it’s freezing and now the lemonade is frozen which makes a solid
The density of a substance is its mass per unit volume, given by the mass divided by the volume. Density depends on the substance of concern and doesn't matter whether one has a little amount of it or a whole full of it. Therefore, the density of the two smaller pieces is now the same as the original density.
Answer:
4.16 g
Explanation:
Volume, V = 2.90 L
STP mans standard temperature and pressure
T = 273 K
P = 1 atm
Mass = ?
Using the ideal gas equation;
PV = nRT
where R = General gas constant = 0.082 L atm mol-1 K-1
n = PV / RT
n = 1 * 2.90 / (0.082 * 273)
n = 2.90 / 22.386
n = 0.130 mol
The relationship between moles and mass;
Mass = number of moles * Molar mass
Mass = 0.130 mol * 32 g/mol
Mass = 4.16 g
