What is the molecular formula of c2h5 if its molecular mass is 90 g?

The molecular formula for butane is C4H10 .

What is the molecular formula of the compound if its empirical formula is c2h4o and the molecular mass is 88?

Molecular formula = C4H8O2. Originally Answered: A compound with the empirical formula CH4O was found to have a molar mass of 84 g/mol.

What is the molecular formula for a compound with a mass of 90 amu and an empirical formula of HCO2?

Explanation: So (1.00794+12.011+2×15.999)⋅g⋅mol−1×n = 90⋅g⋅mol−1 . We solve for n , and clearly n = 2 . So empirical formula is C2H2O4 .

What is empirical formula of compound is ch2o its molecular weight is 90 calculate molecular formula of compound?

Molecular formula weight is 90. So, n=3090​=3. Molecular formula=3×CH2​O. Hence molecular formula is C3​H6​O3​

What’s the molecular formula of C2H5?

What is the molecular mass of C2H5?

3.1Computed Properties

How do you find molecular mass?

Multiply the atomic weight of each element with the number of atoms of that particular element. Similarly, do it for all the elements in the molecule or compound. Add up all the values obtained in the above step. Then add the unit as grams/mole you will get the molecular mass of the substance.

What is a compound molecular formula?

A molecular formula consists of the chemical symbols for the constituent elements followed by numeric subscripts describing the number of atoms of each element present in the molecule. The molecular formula for a compound can be the same as or a multiple of the compound’s empirical formula.

How do you find molecular formula from molecular mass?

Divide the molar mass of the compound by the empirical formula molar mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.

How do you find the molecular mass of Class 9?

What is the molecular mass of the compound C2H5O?

Question 2. A compound is found to have a molecular mass of 90 atomic mass units and simplest formula of C 2H 5O. The molecular formula of the substance is: **Use atomic masses of C = 12 amu, H = 1 amu, O = 16 amu**.

How do you find the molecular mass of a compound?

D. the molecular mass of the substance. A compound is found to have a molecular mass of 90 atomic mass units and simplest formula of C 2 H 5 O. The molecular formula of the substance is: Which sample contains the greatest number of molecules? A sample of potassium chromate, KCrO 4, contains 40.3\% K and 26.8\% Cr.

How do you calculate the molecular formula of CH2O?

Now the molecular formula is always a multiple of the empirical formula; i.e. (EF)n = MF. So 60.0 ⋅ g ⋅ mol−1 = n × (12.011 +2 ×1.00794 +16.00)g ⋅ mol−1. Clearly n = 2, and the molecular formula is 2 ×(CH 2O) = CxH yOz.

What is the simplest form of a compound?

B. the elements that make up one molecule of the substance and the simplest whole number ratio between the atoms. C. the number of molecules in a sample of the substance. D. the molecular mass of the substance. A compound is found to have a molecular mass of 90 atomic mass units and simplest formula of C 2 H 5 O.
