Answer: cause oxegeon is harmful then helium
Explanation:
The molecule<span> is symmetric, a tetrahedron. Thus, the 4 </span>polar bonds <span>cancel each other out.</span>
Molarity is defined by the number of moles of a substance dissolved in a number of liters in solution. 15,000 milliliters is equal to 15 liters, so
2.5/15 = 0.1666... M
The molarity of this solution would be 0.167.
Answer:
The concentration of chloride ion is 
Explanation:
We know that 1 ppm is equal to 1 mg/L.
So, the 
content 100 ppm suggests the presence of 100 mg of in 1 L of solution.
The molar mass of is equal to the molar mass of Cl atom as the mass of the excess electron in is negligible as compared to the mass of Cl atom.
So, the molar mass of is 35.453 g/mol.
Number of moles = (Mass)/(Molar mass)
Hence, the number of moles (N) of present in 100 mg (0.100 g) of is calculated as shown below:
So, there is 
of present in 1 L of solution.
