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

Rudik [331]

Answer:

0.20M

Explanation:

Molarity (by definition) = moles / Volume in Liters

∴Molarity = 0.030mol/0.15Liter = 0.20M

Which of the following solids would possess the lowest melting point?
saul85 [17]
The melting points of the compounds from the choices are listed below:

a. C25H52 -> +47 to +56 degrees celsius 

b. Hg -> -38.83 degrees celsius

c. CaCl2 -> +772 degrees celsius

d. CuO -> +1326 degrees celsius

It is evident from the listed melting points above that mercury (Hg) has the lowest melting point. This is why mercury is liquid at room temperature.
