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.

The combination of potassium-sparing diuretics and salt substitutes can result in dangerously high blood levels of:
alisha [4.7K]

Answer:

b. potassium.  

Explanation:

Potassium-sparing diuretics and salt substitutes are diuretics that eliminate salt and water but save potassium. They act by inhibiting the conducting sodium channels in the collecting tubule, such as amiloride and triamterene, or by blocking aldosterone, such as spironolactone.

Concomitant use of potassium-sparing diuretics together with salt substitutes may result in dangerously high blood levels of serum potassium. For this reason, it is important to consult a physician before taking these substances at the same time to avoid potential problems with potassium accumulation.
