Answer:
volume of 2% saline (V₁) = 0.25ml
volume of water = 4.75ml
Explanation:
The requirement in the question is to obtain 0.1% of NaCl from 2% NaCl, and the process is dilution. The general dilution equation is guven by:
C₁V₁ = C₂V₂
where:
C₁ = initial concentration = 2%
V₁ = initial volume = ?
C₂ = final concentration = 0.1%
V₂ = final volume = 5ml
C₁V₁ = C₂V₂
calculating for V₁
∴ V₁ = (C₂V₂) ÷ C₁
= (0.1% × 5) ÷ 2%
V₁ = 0.25ml
Now, let us calculate the volume of water needed:
V₁ + Volume of water = V₂ (volume of 0.1% NaCl)
0.25 + volume of water = 5
volume of water = 5 - 0.25
volume of water = 4.75ml
The correct answer is (c) Don’t leave your tap running while brushing your teeth, shaving, or washing the dishes. Fix leaky faucets and pipes right away.
As seen in the bar graph that huge amount of water is wasted in the domestic ways. By using the water in adequate amount and saving the water that is wasted while running the tap while brushing and fixing the leaks as soon as possible will save a huge amount of water. The bar graph is covering maximum wastage of water from these sections only. By reducing the water used in brushing, leaky faucets and others can save maximum water.
