# How do you calculate relative formula mass?

## How do you calculate relative formula mass?

To find the relative formula mass (M r) of a compound, you add together the relative atomic mass values (A r values) for all the atoms in its formula. Find the M r of carbon monoxide, CO. Find the M r of sodium oxide, Na 2O. The relative formula mass of a substance, shown in grams, is called one mole of that substance.

What are the chemical properties of calcium carbonate?

CALCIUM CARBONATE is non-combustible. Decomposes at high temperature (825°C) to give gaseous carbon dioxide and calcium oxide (quicklime). Incompatible with acids, alum, ammonium salts, fluorine, magnesium. Reacts with acids and acidic salts to generate gaseous carbon dioxide with effervescence (bubbling).

## What are the benefits of calcium carbonate?

Calcium carbonate can be taken to help increase calcium levels in women whose bones are beginning to soften ( osteopenia) but have not yet developed osteoporosis. Doctors may also prescribe calcium carbonate for people on dialysis to help lower high levels of phosphate in their blood.

## What is the calcium carbonate used for?

Calcium carbonate is a popular dietary supplement used to increase calcium levels. You might see it as a calcium supplement, as an ingredient in antacids, or as an additive in food. Many calcium-fortified foods, including non-dairy “milks,” waffles and cereal bars contain calcium carbonate.

Is calcium carbonate an acid or a base?

1 Answers. Calcium carbonate is neither an acid nor a base, but it is a BASIC SALT. The reason is that Calcium carbonate, CaCO3 is a salt of metal and all salts of metals, when dissolve in water they form basic solution.
