the empirical formula and the molar mass
What else can I help you with?
What is the molecular formula of a compound that has the molar mass of 207?
Without further information, it's not possible to determine the molecular formula of a compound just from its molar mass. Additional details about the elements present and their respective ratios are needed to ascertain the specific molecular formula.
Can molecular formula be used to show difference between isomers?
No, molecular formula alone cannot show the difference between isomers. Isomers have the same molecular formula but different structural arrangements of atoms. Additional information, such as structural formula or connectivity of atoms, is needed to differentiate between isomers.
What information is needed to determine the orientation of the orbital?
Magnetic quantum number (m_l) is needed to determine the orientation of an orbital.
How many hydrogen atoms would be needed in an addition reaction to convert one molecule of 2-pentene to one molecule pentane?
The molecular formula of 2-pentene is C5H10 and the molecular formula of pentane is C5H12. Therefore, (12 - 10) or 2 hydrogen atoms per molecule will be needed to convert pentene to pentane.
What are the steps in writing a molecular compound?
First U have to write the symbols of elements that form the compound, forexample if we want to write the chemical formula of magnesium chloride:1. Mg Cl2. we have to write the valence of each element below itMg Cl2 1then, we switch the valences of each oneso, the chemical formula is going to be:MgCl2
Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
What is the molecular formula of a compound that has the molar mass of 207?
Without further information, it's not possible to determine the molecular formula of a compound just from its molar mass. Additional details about the elements present and their respective ratios are needed to ascertain the specific molecular formula.
What additional information is needed to calculate the molecular formula from the percent by mass of each element in a compound?
In addition to the percent by mass of each element, you also need the molar mass of each element. This information allows you to convert the percent by mass into grams and then into moles, which is necessary to determine the empirical formula and subsequently the molecular formula of the compound.
Can molecular formula be used to show difference between isomers?
No, molecular formula alone cannot show the difference between isomers. Isomers have the same molecular formula but different structural arrangements of atoms. Additional information, such as structural formula or connectivity of atoms, is needed to differentiate between isomers.
How do you find x and y?
More information is needed to determine x and y. Do you have a point on a graph? Are you given a formula?
How can one determine the molecular formula from the given molar mass and percent composition?
To determine the molecular formula from the given molar mass and percent composition, you can follow these steps: Convert the percent composition to grams for each element present in the compound. Calculate the number of moles of each element using the molar mass and the grams of each element. Divide the moles of each element by the smallest number of moles to get the mole ratio. Use the mole ratio to determine the empirical formula. Calculate the empirical formula mass and compare it to the given molar mass to find the multiplier needed to get the molecular formula.
What information is needed to determine the orientation of the orbital?
Magnetic quantum number (m_l) is needed to determine the orientation of an orbital.
What information is needed to calculate the percent composition of a compound?
The formula of the compound and the Atomic Mass of its elements.
What two pieces of information are needed to determine the ratio of elements in a compound?
The chemical formula of the compound (e.g., H2O for water) and the molar masses of the elements present in the compound are needed to determine the ratio of elements. The molar masses are required to calculate the molar ratios of the elements in the compound.
Which two pieces of information about a country are needed to determine its determine its population density?
population and life expectancy
How many hydrogen atoms would be needed in an addition reaction to convert one molecule of 2-pentene to one molecule pentane?
The molecular formula of 2-pentene is C5H10 and the molecular formula of pentane is C5H12. Therefore, (12 - 10) or 2 hydrogen atoms per molecule will be needed to convert pentene to pentane.
How can one determine the volume required to achieve a specific molarity in a solution?
To determine the volume needed to achieve a specific molarity in a solution, you can use the formula: volume (amount of substance) / (molarity). This formula helps calculate the volume of the solution needed to reach the desired concentration.
