What else can I help you with?
If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
How do you find the Molar Proportions of each oxide?
To find the molar proportions of each oxide in a chemical compound, you first determine the molar masses of each element present in the compound. Then, calculate the molar ratio of each element by dividing their molar masses by the smallest molar mass. Finally, simplify the ratios to whole numbers if necessary to obtain the molar proportions.
A sample of a compound contain 1.52 g of Nitrogen and 3.47 g of Oxygen. The molar mass of this compound is between 90 grams and 95 grams. Determine molecular formula and the accurate molar mass.?
A sample of a compound contain 1.52 g of Nitrogen and 3.47 g of Oxygen. The molar mass of this compound is between 90 grams and 95 grams. The molecular formula and the accurate molar mass would be N14O35.
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.
What is the empirical formula of a compound that breaks down into 4.12g of N and 0.88g of H?
To find the answer, the molar ratio of the two elements must be found. The molar mass of hydrogen is 1.0079 and the molar mass of nitrogen is 14.007. From this, it is found that there are approximately .294 moles of nitrogen and .873 moles of hydrogen. By taking and reducing this ratio, it is seen that the compound must be NH3.
What is molar mass a whole number multiple of?
Molar mass is a whole number multiple of the Empirical formula mass
If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
What do the molar masses of any two elements contain the same number of what?
Atoms have atomic weight not molar mass. Any atom-gram has 6,022 141 29(27)×1023 (this is the number of Avogadro) atoms.

What is the molar mass of H2O to the nearest whole number?
18g/mol
What is the relationship between the molar mass of a gas and its density?
The relationship between the molar mass of a gas and its density is that as the molar mass of a gas increases, its density also increases. This means that gases with higher molar masses will be denser than gases with lower molar masses.
How many Buckyballs are in a kilogram?
Buckyballs can be in a range of molar/molecular masses, so the number of them in one kilogram can be very different.
Is it okay to round atomic masses to the nearest whole number?
No, it is not okay to round atomic masses to the nearest whole number because atomic masses are typically reported to several decimal places to account for the average mass of isotopes present in nature. Rounding to the nearest whole number would lead to inaccurate calculations and results.
What are the molar masses of pbBr2?
The molar mass of PbBr2 is 367.008 g/mol
Why do some atoms have a higher molar mass than other atoms?
Atoms have different molar masses primarily due to variations in the number of protons and neutrons in their nuclei. Each element is defined by its atomic number, which corresponds to the number of protons, while the atomic mass reflects the total number of protons and neutrons. Heavier elements tend to have more protons and neutrons, resulting in a greater molar mass. Additionally, isotopes of an element can have different masses due to differing neutron counts.

Is defined as the sum of the atomic masses in the molecule?
This is the molar mass.
