The number of Ml of 0.80 M sucrose solution that contain
(A) 7.45 g are 27.25 Ml
<u>calculation</u>
volume= moles /molarity
molarity = 0.80 M which is the same as 0.80 mol/l
moles= mass/molar mass
= 7.45 g/ 342.3 g/mol =0.0218 moles
volume is therefore = 0.0218 moles / 0.80 mol/L=0.02725 L
convert into ml by multiplying by 1000
= 27.25 ml
<h3>
<u>
question b</u></h3>
volume = moles/molarity
molarity = 0.80 M = 0.80 Mol/L
moles =mass/molar mass
mass 17.0 mg convert into g by diving by 1000=0.017 g
moles is therefore = 0.017 g/ 342.3 g/mol = 4.97 x10^-5 moles
volume = (4.97 x 10^-5 moles) /0.8 mol /l=6.21 x10^-5 L
= 6.21 x10^-5 x 1000 =0.0621 Ml
Answer:
Hey,
So what you would do here is first choose a biome, such as the desert for example, then choose an organism that lives there, or an animal. Then think of what it is like where it lives, is it dry, cold, windy, and so force, just describing the place by its looks and climate. How would this population increase, maybe it would be if there was suddenly more food there for them, or if their ecosystem got better for them to live, then, if they populated more, how would that affect the ecosystem. Maybe some animals would die off more, or some would have to much food. Like what if the fly population suddenly doubled, for example, how would that affect the ecosystem? Now what would happen if that organism was removed? If flies were removed, spiders and a lot of other organisms would not have food, and some organisms would overpopulate because nothing would eat them. That is just an example.
