How would you make 2.5 liters of an aqueous solution containing 150mM Tris (the MW of Tris is 120g/mole)? (Hint: Do the necessar
lisabon 2012 [21]

Answer:

45 g of the solid Tris will be dissolved in 2.5 liters of water.

Explanation:

Recall that:

<em>Number of moles  = molarity x volume</em>

Hence, number of moles of Tris present in 2.5 liters, 150 mM solution:

= 150/1000 x 2.5 = 0.375 moles

Also, recall that:

<em>No of moles of substance = mass/molar mass.</em>

Hence, mass of 0.375 moles substance:

= no of moles of the substance x molar mass of the substance.

= 0.375 x 120 = 45 g.

Therefore, in order to prepare 2.5 liters, 150 mM of an aqueous solution of Tris, 45 g of the solid Tris will be dissolved in 2.5 liters of water.

Describe two ways that water moves through the earths biosphere in the water cycle
Iteru [2.4K]
<span>For the first one I would say that the water cycle would be affected because there would be more water in the ground. The roots of the trees soak up the water and keep excellent drainage under the ground. Without trees this mechanism would be all sorts of messed up. Another way it could be affected would be the perspiration from the trees. This might change the humidity of the area.</span>
