Question

given 357 g of c2h4o, determine the number of moles of c2h4o. 1 mol c2h4o = 44.05 g c2h4o ? mol c2h4o = 357 g c2h4o round your answer to two decimal places.

Explanation:

Step1: Identify the conversion factor

We know that 1 mol of $C_2H_4O$ has a mass of 44.05 g. We want to find the number of moles for 357 g of $C_2H_4O$.

Step2: Set up the calculation

Use the formula $n=\frac{m}{M}$, where $n$ is the number of moles, $m$ is the mass and $M$ is the molar - mass. Here, $m = 357$ g and $M=44.05$ g/mol. So $n=\frac{357}{44.05}$.

Step3: Calculate the result

$n=\frac{357}{44.05}\approx8.11$ mol.

Answer:

8.11
