Answer:
4.62 M
Explanation:
Molarity = moles/volumes (L), so you need to find the moles and the volumes in liters.
Finding the volume is easy because you just have to convert mL to L, so the volume is 0.45 L
Next, find the moles. You can do this by using the molar mass of aluminum to convert the grams to moles. The molar mass of aluminum is 26.98 g/mol.
56 g * (1 mol/26.98 g) = 2.08 mol
Now, divide the moles (2.08) by the volume (.45 L)
Molarity = 4.62 M
Answer:
Fluorometric emission scanning.
Explanation:
Fluorometric emission scanning is used to detect the presence of porphyrins. There are various types of porphyrins and they can be tested in a lab with either, urine or blood sample testing.
This question can be explained in a variety of ways, but the easiest can be that elements exist, and since each has a different atomic mass, all atoms are not identical in size and mass.
Answer:
Explanation:
Hello,
For the given chemical reaction:
Whose heat of reaction is 464.8 kJ/mol which means that energy is absorbed due to the chemical reaction, we can compute the moles of calcium carbide via the following relationship:
Then, since the molar mass of calcium carbide is 64 g/mol, the yielded mass turns out:
Best regards.
Carbonated water would be what you are looking for :v)
