Answer:
625 mL
Explanation:
From the question given above, the following data were obtained:
Volume of stock solution (V₁) = 250 mL
Molarity of stock solution (M₁) = 5 M
Molarity of diluted solution (M₂) = 2 M
Volume of diluted solution (V₂) =?
The volume of the diluted solution can be obtained by using the dilution formula as illustrated below:
M₁V₁ = M₂V₂
5 × 250 = 2 × V₂
1250 = 2 × V₂
Divide both side by 2
V₂ = 1250 / 2
V₂ = 625 mL
Therefore, the volume of the diluted solution is 625 mL.
Answer:
C5H10O5
Explanation:
The molecular formula is a multiple of the empirical formula. I.e
Molecular formula => [CH2O]n
[CH2O]n = 150
[12 + (2x1) + 16 ]n = 150
30n = 150
Divide both side by the coefficient of n i.e 30
n = 150/30 = 5
Molecular formula => [CH2O]n
Molecular formula => [CH2O]5
Molecular formula => C5H10O5
Answer:
The various species raised today are distinguished by the quality of the silk they produce. Silkworms feed on the leaves of the mulberries (genus Morus) and sometimes on the Osage orange (Maclura pomifera). Bombyx Mori will not bite, making it an ideal worm for feeding most reptiles, amphibians and other animals.
