Its not that hard.
Half of the inch part is 1/2 inch which is also 4/8.
half of the 3/4 part is 3/8 you get by multiplying the denominator by 2.
Put it all back together and you get the 4/8 part and the 3/8 part so in total its 7/8 of an inch.
How many grams are in magnesium?
-
The relative masses of each element can be found on the periodic table. For example, one atom of magnesium weighs 24.31 amu (atomic mass units). However, one mole of magnesium weighs 24.31 g.
-
1 gram (g) is equal to 1000 milligrams (mg).
Additionally, how do you calculate moles of magnesium? Calculating the mass of products
- 2.43 g of magnesium reacts completely with excess hydrochloric acid to form magnesium chloride and hydrogen:
- Mg(s) 2HCl(aq) MgCl 2(aq) H 2(g)
- Calculate the maximum mass of hydrogen that can be produced. (
- number of moles of Mg =
- = 0.100 mol.
Consequently, what is the RFM for magnesium?
The relative atomic mass of an element shows its mass compared with the mass of atoms of other elements. The relative atomic mass of carbon is 12, while the relative atomic mass of magnesium is 24. This means that each magnesium atom is twice the mass of a carbon atom.
What makes up a gram?
In weight, a gram is equal to a thousandth of a kilogram. In mass, a gram is equal to a thousandth of a liter (one cubic centimeter) of water at 4 degrees centigrade. The word gram comes from the Late Latin gramma meaning a small weight via the French gramme. The abbreviation for gram is gm.
