Question

calculate the molecular formula for a compound with a molar mass of 150.0 g/mol and an empirical formula of ch₂o.
step 1: calculate the molar mass for the empirical formula.
what is the molar mass of ch₂o?
(c = 12.01 amu, h = 1.01 amu, o = 16.00 amu)
? g/mol ch₂o

Explanation:

Step1: Calculate molar mass of each element in the formula

• For C: \(1\times12.01\ \text{g/mol}=12.01\ \text{g/mol}\)
• For H: \(2\times1.01\ \text{g/mol}=2.02\ \text{g/mol}\)
• For O: \(1\times16.00\ \text{g/mol}=16.00\ \text{g/mol}\)

Step2: Sum up the molar masses

Answer:

\(30.03\ \text{g/mol}\)
