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

What is most likely the ph of a solution containing many hydroxide ions (oh-) and few hydrogen ions (h )?
SIZIF [17.4K]
PH of solution will be greater than seven (pH>7), that means that solution is basic (<span>pH above </span>7<span> is a base, the higher the number, the stronger is the base).
</span>pH (potential of hydrogenis) is a measure of the hydrogen ion (H⁺) concentration of a solution. <span>Solutions with a pH less than 7 are acidic.</span>
