Answer:
of sodium arsenate would be present in a 1.70 L sample of drinking water that just meets the standard.
Explanation:
Mass of sodium arsenate =x
Mass of water = M
Density of water = d = 1000 g/L
Volume of the water , V= 1.70 L
M =
1 Parts per billion = 1 μg/kg =
(1 kg =1000 g)
Moles of arsenic =
1 mole of sodium arsenate has 1 mol of arsenic atom.Then of arsenic will found in:
of sodium arsenate.
Mass of of sodium arsenate:
of sodium arsenate would be present in a 1.70 L sample of drinking water that just meets the standard.
You add (only) the protons and neutrons, so the answer here is 58
no, it contains 3 basic particles. (protons, electrons, neutrons)
hope this helped
