Answer:
The correct answer is 0.11 L
Explanation:
From the problem, we have the following data:
moles CaCl₂= 0.039 mol
molarity = 0.340 M = 0.340 mol CaCl₂/L
According to this, the solution has 0.340 mol of CaCl₂ in 1 L. If the total number of moles is 0.0369, we can find the volume as follows:
V= moles/molarity = 0.0369 mol x 1 L/0.340 mol = 0.108 L ≅ 0.11 L
Answer:
9.38 moles NaNO₃
Explanation:
Given the measurements provided, the best way to find moles is by using the molarity formula. The molarity formula is:
Molar concentration (M) = moles / volume (L)
Therefore, plug the provided values into the formula, then isolate to find moles.
Molar concentration (M) = moles / volume (L)
0.750 M = moles / 12.5 L
(0.750 M) x (12.5 L) = moles
9.38 = moles

I think they are primary producers, as they produce biomass from inorganic compounds (CO2)
