A stream seems to be the best answer
Answer:
2.448 M ≅ 2.45 M.
Explanation:
Molarity (M) is the no. of moles of solute that dissolved in 1.0 L of the solution.
M = (no. of moles of solute)/(V of the solution (L).
M = (mass/molar mass) Li₂S / (V of the solution (L))
<em>∴ M of Li₂S</em> = (500.0 g/46.4 g/mol)/(4.44 L) = <em>2.448 M ≅ 2.45 M.</em>
Answer:
a. H
b. H
c. N
d. N
Explanation:
a. Human error - It should be their responsibility to calibrate the balance
b. Human error - they should've known to put the right amount of sig figs.
c. Nonhuman error - they can't control the temperature
d. Nonhuman error - the balance must've been broken, therefore not a human error
