Consider the Chemical Reaction first:
Reaction: H₂SO₄ + 2 NaCl → 2 HCl + Na₂SO₄
Now, Given mass of NaCl = 30 g
Molar mass of Nacl = 58 g/mol
Now, Number of moles of NaCl = 30/58 = 0.517 mol
Balance the equation, For every 2 molecules of NaCl, 2 molecules of HCl formed, so the number of moles would be same.
Hence, Number of moles of HCl = 0.517 mol
Now, Mass of HCl = Molar mass of HCl * Number of moles
Mass = 36 * 0.517 [ Molar mass of HCl = 36 ]
Mass = 18.62 g
In short, Your Answer would be: 18.62 Grams
Hope this helps!
None of them really sound like the answer, but my best guess would probably be the second one. It doesnt give much info.
A theory is like a hypothesis like an idea. Observation is to gain information like taking notes about what you see.
Answer:
Kilogram
Explanation:
The metric system is the Kilogram, meter, second system. These are fundamental quantities of the metric system.
Kilogram, the unit of mass always carries the prefix 'kilo' in its SI unit. Kilogram is the SI unit of mass. Hence, the fundamental unit on the metric system that always has a prefix in front of it is kilogram.
