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
g/mol ch₂o

Explanation:

Step1: Calculate molar mass of each element in the formula

• Molar mass of \(C\): \(1\times12.01 = 12.01\) g/mol
• Molar mass of \(H\): \(2\times1.01=2.02\) g/mol
• Molar mass of \(O\): \(1\times16.00 = 16.00\) g/mol

Step2: Sum up the molar masses

$$12.01+2.02 + 16.00=30.03$$ g/mol

Answer:

\(30.03\) g/mol
