The given question is incomplete. The complete question is:
Calculate the number of moles and the mass of the solute in each of the following solution: 100.0 mL of 3.8 × 10−5 M NaCN, the minimum lethal concentration of sodium cyanide in blood serum
Answer: The number of moles and the mass of the solute are 
and 
respectively
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
n = moles of 
= 
Thus the number of moles and the mass of the solute are and respectively
Answer:
what each cells job is divided
Explanation:
The last row going across
Because the scale is much larger, and a larger pool can collect more energy than a small pool, and it is more likely that it would have more energy spread throughout it.
Answer:
a. True
