a relief valve is inserted in the downstream line from the pressure regulator.
Explanation:
Whenever dry nitrogen from a portable cylinder is used in service and installation practice the item of most importance in consideration of safety is a relief valve is inserted in the downstream line from the pressure regulator.
First, convert grams of the elements to moles. Then you divide by the smallest number of moles to get the lowest whole number ratio.
86g C×1 mol C/12g C = 7.2 mol C/7.2= 1
14 g H×1 mol H/1g H = 14 mol H/7.2= 2
So the empirical formula is C1H2
Answer:
8.801×10^-18 moles Ca
Explanation:
5.3 X 10^6atoms* (1mol/6.022*10^23) = 8.801×10^-18 moles Ca
