(i) The sodium ion (Na+) is larger than the magnesium ion (Mg2+) due to two effects.

The MassDEP has established a guideline of 20 milligrams of sodium per liter of water (mg/L). If sodium is measured in drinking water at a level above 20mg/L, it is important for people who may be on a very low sodium or sodium restricted diet to know.

The answer is 58.44277. We assume you are converting between grams NaCl and mole. You can view more details on each measurement unit: molecular weight of NaCl or mol This compound is also known as Sodium Chloride. The SI base unit for amount of substance is the mole.

A certain amount of univalent ions provides the same amount of equivalents while the same amount of divalent ions provides twice the amount of equivalents. For example, 1 mmol (0.001 mol) of Na+ is equal 1 meq, while 1 mmol of Ca++ is equal 2 meq.

What is the difference between milligrams (mg) and millilitres (mL)? Milligrams (mg) measure weight, and Millilitres (ml) measure volume of liquid. The part of the word 'Milli' comes from the latin mille, which means one thousand. There are 1,000 milligrams in a gram, and 1,000 millilitres in a litre of liquid.

mass Na atom = 22.99 g Na/mole x 1 mole/6.023 x 1023 atoms = 3.817 x 10-23 g.

Is 1 ML = 1000 MG. Milligram (mg): Milligram is a unit of measurement of mass which is equivalent to 1/1000 of a gram.

A gram of salt clocked in at about 1/6 tsp, making it the heaviest ingredient. But salt is composed of chloride as well, with only 40% of its weight accounting for pure sodium. Doing some math there gives us about a 1/2 tsp of salt to amount to 1 gram of sodium.

Answer: Yes, 3/4 is bigger than 1/2. You can confirm this by converting both fractions to decimals.

As a general rule, elements get larger from right to left and top to bottom. The ionic size gets a little muddled since metals and nonmetals form ions in different ways. Since metals lose electrons when they form ions, they get smaller, while nonmetals gain electrons and get bigger.

Milligrams (mg) measure weight, and Millilitres (ml) measure volume of liquid. ... There are 1,000 milligrams in a gram, and 1,000 millilitres in a litre of liquid.

Sodium atom is neutral whereas sodium ion is a charged specie with a charge of +1. The number of protons and electrons in sodium atom is same i.e 11 whereas the number of protons in sodium ion (11) is more than number of electrons (10). The size of sodium ion is smaller than sodium atom.

In general, anions are larger than the corresponding neutral atom, since adding electrons increases the number of electron-electron repulsion interactions that take place. Cations are smaller than the corresponding neutral atoms, since the valence electrons, which are furthest away from the nucleus, are lost.

Sodium 371 Giant metallic lattice, lots of strong metallic bonds to break so high melting point. Magnesium 922 Giant metallic lattice, lots of strong metallic bonds. More delocalised electrons added to sea of electrons, 2e per atom.

depends on the density. mg is a measure of mass and ml a measure of volume. If we are taking water than the density is very close to 1 kg per liter or 1 g per ml. 5 mg is 5/1000 g and that volume of water would be very close to 5/1000 ml or 0.005 ml.

From IU to mg: IU * 0.67 = mg. From mg to IU: mg * 1.5 = IU see less In the metric system, 1000 milligrams (mg) is a unit of mass equal to 1 gram and 1000 micrograms (mcg) is equal to 1 milligram (mg). An IU (International Unit) is a unit of measurement for vitamins and other specific biologically active substances.
