That is extremely confusing. Try contacting your prof.
Explanation:
Answer:
D. 23.9 liters
Explanation:
- Molarity is defined as the no. of moles of solute dissolved in 1.0 L of the solution.
M = (no. of moles)solute / (V of the solution (L))
M = (mass/molar mass)NaCl / (V of the solution (L))
M = 0.03 M, mass of NaCl = 42.0 g, molar mass = 58.44 g/mol.
∴ V of the solution = (mass/molar mass)NaCl / M = [(42.0 g/58.44 g/mol)] / (0.03 M) = 23.96 L.
<em>So, the right choice is: D. 23.9 liters</em>
C. CH3OH
hope this helped! :))
Answer:
C. A stretch of raised land, often built to help control flooding and the flow of a river.
Explanation:
Embankments are made typically of construction adjacent to the river from spoil excavated from its bank.
Hey there!
There are 6.022 x 10²³ particles in 1 mole.
We have 3.55 moles.
6.022 x 10²³ x 3.55
2.14 x 10²⁴
This is how many particles we have.
NaCl has 2 atoms for every unit.
So we multiply this by 2.
2 x 2.14 x 10²⁴ = 4.28 x 10²⁴
There are 4.28 x 10²⁴ atoms in 3.55 moles of sodium chloride.
Hope this helps!
