Q1) The best description for molecule b in the diagram is adenosine diphosphate because there are only two phosphate groups. (b)

Q2) I would say b again, but I am not 100% sure. In the diagram, ATP seems to have given off a phosphate group and become ADP. The other answers are all not specified in the diagram, but rather inferences from what might be happening.

A saline solution used in intravenous drips for patients who cannot take oral fluids contains 0.92% (w/v) NaCl in water. How man

Effectus [21]

Answer:

2.3 g NaCl

Explanation:

Given the concentration of the NaCl solution = 0.92% (w/v)

It means that 0.92 g of NaCl is present in 100 mL of water.

Thus,

100 mL of water contains 0.92 g of NaCl

To find, amount of NaCl in 250 mL of water

So,

1 mL of water contains $\frac {0.92}{100}\ g$ of NaCl

250 mL of water contains $\frac {0.92}{100}\times 250\ g$ of NaCl

2.3 g of NaCl is present in 250 mL of this solution.
