The empirical formula for a compound is ch2o and the molar mass is 180.2g mol which is molecular formula for this compound
elena-14-01-66 [18.8K]
Answer:
                Molecular Formula  =  C₆H₁₂O₆

Solution:

Molecular formula is calculated by using following formula,

                     Molecular Formula  =  n × Empirical Formula  ---- (1)

Also, n is given as,

                      n  =  Molecular Weight / Empirical Formula Weight

Molecular Weight  =  180.2 g.mol⁻¹

Empirical Formula Weight  =  12 (C) + 2 (H₂) + 16 (O)  =  30 g.mol⁻¹
Son
                      n  =  180.2 g.mol⁻¹ ÷ 30 g.mol⁻¹

                      n  =  6

Putting Empirical Formula and value of "n" in equation 1,

                     Molecular Formula  = 6 × CH₂O

                     Molecular Formula  =  C₆H₁₂O₆

How are ironic bonds and covalent bonds different and how are they different?
Vinil7 [7]
Ionic bonds are forces that hold together electrostatic forces of attractions between oppositely charged ions. Ionic bonds have an electronegativity difference greater than or equal to 2. Covalent bonds have an electronegativity difference that is less than 2.

Answer:

iron is less reactive

Explanation:

therefore it will be extracted using carbon as it forms less stable oxides so little energy is needed to extract the metal.

14. A 500.0 ml flask contained O2 gas at 25.0°C at a pressure of 4.5 atm. What is the number
Luden [163]

Explanation:

3.Apply the ideal gas law: PV = nRT solving for n. Here you can use the pressure given in atm, but you must choose the 0.0821 atm L/mole K gas constant. Or you can change 4.5 atm to 3420 mm Hg and use the 62.4 mmHg L/mole K gas constant. You must change 500 ml to 0.5 L because both gas constants have units in L, and so the volume must be in liters so it can cancel out. And of course, you must change the temperature to Kelvin.

a. n = (4.5atm)(0.5L)

moliK)(298K) = 0.092 mole (0.0821 atmiL

b. 0.092mol 32g

⎛⎝⎜ ⎞⎠⎟ = 2.9 g

1mol

c. Remember that D = mass

vol so D = 2.9g

0.5L = 5.9 g/L

Softa [21]
The answer is hyperbaric medicine.

Hyperbaric medicine is a treatment in which is necessary a chamber with  pressure greater than sea level atmospheric pressure. Is intended to reduce the effects of systemic gas bubbles by reducing their size and lead to their elimination.
