In dilution we add distilled water to decrease the concentration of required sample from high concentration to lower concentration
The law used for dilution:
M₁V₁]Before dilution = M₂V₂] After dilution
M₁ = 1.5 M
V₁ = ?
M₂ = 0.3 M
V₂ = 500 ml
1.5 * V₁ = 0.3 * 500 ml
so V₁ = 100 ml and it completed to 500 ml using 400 ml deionized water
Answer:
3,200 joules
Explanation:
q = mcΔT = (250.0 g)(0.128 j/g°C)(100°C -25°C) = 3,200 joules
This is how you convert gallons to liters.
- Gallon is a volumetric unit.
- 1 gallon equals 3.785 liters
- So, you create this conversion factor: 1 gal = 3.785 liter ⇒ 1 = 3.785 liter / 1 gallon.
- Therefore, you can multiply any amount in gallons by the conversion factor and get the equivalent amoun in liters.
- Examples:
- 1 gallon = 1 gallon × 3.785 liter / gallon = 3.785 liter
- 3 gallon = 3 gallon × 3.785 liter / gallon = 11.355 liter
- 15.25 gallon = 14.25 gallon × 3.785 liter / gallon = 53.936 liter
Answer:
Without the respiratory system your blood would be useless. The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body
