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
Ya you are right, it is generator which is used to convert mechanical energy to electrical energy !
The Calvin Cycle begins when energy in the form of light is converted into chemical energy.
A temperate forest is likely
to have numerous flowers from flowering
plants. Flowers are an evolutionary trend in flowering plants to attracts animals to
facilitate pollination. The flowers contain nectar that attracted birds, bees and other
nectar-sucking animals. The nectar is produced by nectaries
in hollow
tube in the flowers. Therefore for birds to access
the nectar they require to have long slender beaks as an adaptaition.
