Answer:
This concentrations represents 9.71 x 10¹⁹ nitrate ions per litre of drinking water.
Explanation:
Nitrate: NO₃⁻
MW = 62.00 g/mol
1 mol = 6.022 x 10²³
62 g NO₃⁻ ____________ 6.022 x 10²³ ions
10 x 10⁻³ g NO₃⁻ _________ x
x = 9.71 x 10¹⁹ ions
This concentrations represents 9.71 x 10¹⁹ nitrate ions per litre of drinking water.
It's an insulator
conductors conduct electricity well while insulators do not
