Question

given 382 g of ch₂cl₂, determine the number of moles of ch₂cl₂. 1 mol ch₂cl₂ = 84.93 g ch₂cl₂ ? mol ch₂cl₂ = 382 g ch₂cl₂ round your answer to two decimal places.

Explanation:

Step1: Use the formula for moles

The formula for calculating the number of moles \(n\) is \(n=\frac{m}{M}\), where \(m\) is the mass and \(M\) is the molar mass. Here, \(m = 382\space g\) and \(M=84.93\space g/mol\).

Step2: Substitute the values into the formula

$$n=\frac{382\space g}{84.93\space g/mol}$$

Step3: Calculate the value

$$n=\frac{382}{84.93}\approx4.50\space mol$$

Answer:

\(4.50\)
