What else can I help you with?
Why is a graph of the amount of a particular element in moles versus the mass of element in grams is a straight like?
Because the relation is of proportionality.
What is the molar amount?
The molar amount refers to the number of moles of a substance present in a given sample. It is calculated by dividing the mass of the substance by its molar mass. Molar amount is typically expressed in moles.
Do you find the number of moles of an element?
Use avagadro's number - states the number of atoms in 1 mole of a substance: 6.022 x 10^23
How do you convert an element to moles?
to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g. So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams Hoped this helped : )
How would we know how many moles are in a certain element?
number of moles = mass of the element/molar mass of the element
Why are different amounts of each element required to react with the same amount of hydrogen?
Different amounts of each element are required to react with the same amount of hydrogen because each element has a different molar mass and reacts in different stoichiometric ratios. The stoichiometry of the reaction depends on the balanced chemical equation for the reaction, which determines the number of moles of each reactant needed to fully react with the given amount of hydrogen.
How is stoichiometry used to calculate amount of product from amount of reactant?
The coefficients give the ratio of moles reactant to moles product.
How is the mass in grams of an element converted to amount in moles?
1 mol of any element is the atomic weight expressed in grams.
Why is a graph of the amount of a particular element in moles versus the mass of element in grams is a straight like?
Because the relation is of proportionality.
Where can you find a solution to problem solving number of moles in a given element?
Number of moles = Mass of the sample in g/Molar mass in g
How many liters of oxygen is required for the combustion of 39 grams of liquid benzene?
To find the amount of oxygen required for the combustion of liquid benzene, you would need to balance the combustion reaction equation for benzene. Calculate the moles of benzene from the given mass, then use the stoichiometry of the balanced equation to determine the moles of oxygen required. Finally, convert the moles of oxygen to liters using the ideal gas law.
How to find the volume when given molarity and moles?
To find the volume when given molarity and moles, use the formula: volume moles / molarity. This formula helps calculate the volume of a solution based on the amount of solute (moles) and the concentration of the solution (molarity).
What is the molar amount?
The molar amount refers to the number of moles of a substance present in a given sample. It is calculated by dividing the mass of the substance by its molar mass. Molar amount is typically expressed in moles.

How is the number of moles of an element determined froma known mass?
To determine the number of moles of an element from a known mass, you use the element's molar mass (grams per mole). Simply divide the given mass of the element by its molar mass to calculate the number of moles. This relationship is described by the formula: moles = mass (g) / molar mass (g/mol).
How can one determine the amount of moles in a given substance?
To determine the amount of moles in a substance, you can use the substance's mass and molar mass. Divide the mass of the substance by its molar mass to calculate the number of moles. This formula is represented as moles mass / molar mass.
