Answer:the other vaiabable
Explanation:
Answer: 1,762.97 ft² ≈ 1,763 ft²
Explanation:
1) Conversion factor:
1 ft = 0.305m ⇒
1 = 1 ft / 0.305m ⇒
´[1]² = [1 ft / 0.305m]² ⇒
1 = 1 ft² / (0.305m)² ⇒
1 = 1 ft² / 0.093025 m²
2) 164 m²
164 m² × 1 ft² / 0.093025 m² = 1,762.97 ft² ≈ 1,763 ft²
The amu is a unit which means the mass per neutron, So the 74.55 means the mass per mole KCl. So the mole number of 2.330g KCl is 2.330/74.55=0.031 mol. The volume is 0.031/0.1250=0.248 L ≈ 250 mL. So the answer is a.
b, the sunlight decreases because the sun is tilted on an axis and towards the fall and winter times, it gets shorter
