Convert 2.0 mEq/L of magnesium to milligrams per deciliter. What is the result?

Convert 2.0 mEq/L of magnesium to milligrams per deciliter. What is the result?

• A. 0.8 mg/dL
• B. 1.2 mg/dL
• C. 2.4 mg/dL
• D. 4.9 mg/dL

Answer: (C)

To convert milliequivalents per liter (mEq/L) of magnesium to milligrams per deciliter (mg/dL), one needs to consider the molecular weight of magnesium and the valency of magnesium in this case. Magnesium has a molecular weight of approximately 24.3 g/mol and its valency is 2, which means one mole of magnesium can produce two equivalents. The conversion from mEq/L to mg/dL involves a few steps: 1. **Calculate the amount in grams**: Since magnesium has a valency of 2, you divide the molecular weight by the valency to convert to equivalents: - 24.3 g/mol / 2 = 12.15 g/equiv. 2. **Convert from grams to milligrams**: Since there are 1,000 mg in 1 g, for 1 equivalent of magnesium: - 12.15 g/equiv. is now 12,150 mg/equiv. 3. **Apply the conversion**: Now, to find out how many milligrams are in 2.0 mEq/L: - 2.0 mEq/L * 12,150 mg/equiv

To convert milliequivalents per liter (mEq/L) of magnesium to milligrams per deciliter (mg/dL), one needs to consider the molecular weight of magnesium and the valency of magnesium in this case.

Magnesium has a molecular weight of approximately 24.3 g/mol and its valency is 2, which means one mole of magnesium can produce two equivalents. The conversion from mEq/L to mg/dL involves a few steps:

1. Calculate the amount in grams:

Since magnesium has a valency of 2, you divide the molecular weight by the valency to convert to equivalents:

• 24.3 g/mol / 2 = 12.15 g/equiv.

2. Convert from grams to milligrams:

Since there are 1,000 mg in 1 g, for 1 equivalent of magnesium:

• 12.15 g/equiv. is now 12,150 mg/equiv.

3. Apply the conversion:

Now, to find out how many milligrams are in 2.0 mEq/L:

• 2.0 mEq/L * 12,150 mg/equiv
