The molecular formula mass of this compound is 210 amu What are the subscripts in the actual molecular formula Enter the subscripts for C H and O?
Given the molecular formula mass of 210 amu, the subscripts for C, H, and O in the actual molecular formula can be determined as follows: the atomic mass of carbon (C) is 12 amu the atomic mass of hydrogen (H) is 1 amu the atomic mass of oxygen (O) is 16 amu Thus, the subscripts for C, H, and O are calculated as follows: Subscript for C: 210 amu / 12 amu = 17.5 (approx. 18) Subscript for H: 210 amu / 1 amu = 210 Subscript for O: The compound doesn't contain oxygen since the sum of 18 (C) and 210 (H) exceeds 210, which is the given molecular formula mass.
What is the AMU of carbon?
AMU stands for atomic mass units; the number of units an element has is called its atomic mass. The atomic mass of carbon is exactly 12, by definition.
What is the formula mass of calcium fluoride CaF2?
The formula mass of calcium fluoride (CaF2) can be calculated by adding the atomic masses of calcium (Ca) and two fluorine (F) atoms. The atomic mass of Ca is approximately 40.08 g/mol, and the atomic mass of F is approximately 19.00 g/mol. Thus, the formula mass of CaF2 would be approximately 40.08 + 2(19.00) = 78.08 g/mol.
What is the molecular formula of ethylene glycol if mass is 62amu?
The molecular formula of ethylene glycol is C2H6O2. Given that the molar mass of ethylene glycol is 62 amu, it confirms that the molecular formula is correct, as the sum of the atomic masses of carbon (C), hydrogen (H), and oxygen (O) in one molecule of ethylene glycol equals 62 amu.
What element forms a diatomic gas with a mass of 160 amu?
Bromine (Br) has a molar mass of 79.904 amu (atomic mass units), which is extremely close to 80. Bromine is diatomic so when two bromine molecules are put together to create a diatomic gas, the molar masses of each bromine add to get a combined molar mass of 160 amu.

What is the formula mass of magnesium perchlorate?
The formula mass of magnesium perchlorate (Mg(ClO4)2) can be calculated by adding the atomic masses of magnesium, chlorine, and oxygen in the compound. The atomic mass of magnesium is 24.305 amu, chlorine is 35.453 amu, and oxygen is 16.00 amu. Therefore, the formula mass of magnesium perchlorate is 24.305 + 2(35.453) + 8(16.00) = 223.21 amu.
How do you calculate the mass of tritium?
Tritium has two neutrons and one proton: the mass is 3 amu.
What is the formula of the formula mass?
Mass = weight /gravity Density = Mass / Volume So, if you know the density and the volume, you can calculate the mass. Also, you can measure the mass by measuring the weight. On earth, mass and weight are equal.
Determine the molecular formula for the unknown if the molecular mass is 60.0 amu and the empirical formula is CH2O.?
To determine the molecular formula from the empirical formula CH2O and given molecular mass of 60.0 amu, calculate the empirical formula mass: (12.01 g/mol for C) + 2(1.01 g/mol for H) + 16.00 g/mol for O = 30.02 g/mol. Then divide the given molecular mass by the empirical formula mass to find the factor by which the empirical formula must be multiplied to get the molecular formula: 60.0 amu / 30.02 g/mol ≈ 2. Next, multiply the subscripts in the empirical formula by this factor to find the molecular formula: 2(C)2(H)2(O) = C4H4O2, giving the molecular formula as C4H4O2.
The formula mass of a molecule or an ion is?
