What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
Answers
Answer:
1 gram molecular mass of this compound = 20
Explanation:
Gram Molecular Mass is the mass of a chemical that is obtained by the number of grams in the chemical determined by the masses obtained from the periodic table and the number of mols determined from the Chemical formula.
That's quite a mouthful. Here's what it means in plain language.
Find the Gram molecular mass of C2H6
The periodic table tells us that 1 mol of C2H6 has
2 mols of Carbon which is 2*C or 2 * 12 = 24 and
6 mols of Hydrogen which is 6*H or 6*1 = 6
The gram molecular mass is 6 + 24 = 30
Your question doesn't require all that background.
5 gram molecular masses = 100 grams Given
1 gram molecular mass = x
5/1 = 100/x Cross multiply
5x = 100 Divide by 5
x = 100 / 5
x = 20
The gram molecular mass of a compound whose 5 moles has a mass of 100 grams would be 20 grams per mole.
The gram molecular mass of a substance is simply the mass (in gram) of 1 mole of the same substance. In other words, the gram molecular mass of a substance is also the same as the molar mass of the substance.
In this case, 5 moles of the substance weigh 100 grams
Therefore, 1 mole of the same substance would weigh:
1 x 100/5 = 20 grams

Answer:
potassium and sodium
Explanation:
There are many metals that can react with aluminium nitrate in a displacement reaction. these metals are higher than aluminium in the electrochemical series of elements where metals are arranged based on their reactivity and therefore tend to displace aluminium in any chemical reaction. However the most reactive of these metals are potassium(K) and sodium(Na). Others are calcium(Ca), magnesium(Mg), lithium(Li), strontium (Sr).

Starch is a carbohydrate which is a polysaccharide and not a simple sugar like glucose, fructose,etc.
What are carbohydrates?
A carbohydrate is defined as a bio-molecule which consists of carbon,hydrogen and oxygen atoms which are usually in the ratio of 2:1 with the empirical formula C(H₂O)
.
This term is most commonly used in biochemistry as a synonym of saccharide which is a group of sugars, starch and cellulose.
They perform various functions in living organisms. They serve as an energy source and as well as structural components . They are a key component in providing nutrition and are found in wide variety of natural as well as processed foods.
Carbohydrates occur as cellulose in the cell walls of plants and is one of the components of insoluble dietary fibers.
