Answer:
7.99 mol
Explanation:
Step 1: Given data
Molecules of chlorine gas: 4.81 × 10²⁴ molecules
Step 2: Calculate how many moles of chlorine gas corresponds to 4.81 × 10²⁴ molecules of chlorine gas
In order to convert molecules to moles, we will use Avogadro's number: there are 6.02 × 10²³ molecules of chlorine gas in 1 mole of molecules of chlorine gas.
4.81 × 10²⁴ molecules × (1 mol/6.02 × 10²³ molecules) = 7.99 mol
Answer:

14.634 g H20 was left over
Explanation:
They are studying the planet's ecosystem.
Answer:
80.7 L
Explanation:
PV = nRT
P = 1520 mmHg = 2 atm
n = 5 mol
R = 0.08206 (L * atm)/(mol * K)
T = 393.15 K
2 (V) = 5 (0.08206) (393.15)
V ≈ 80.7 L
