Question

How many grams are in a 4.1 mole sample of CO?

Answer 1

114.841 grams

Step-by-step explanation

Given:

Moles of C = 4.1 mol

What to find:

Mass in grams of CO in 4.1 moles of CO.

Solution:

The first steF is to find the molar mass of CO.

rom the periodic table, the atomic masses of (C = 12.011, O = 15.999)

Molar mass of CO = 12.011 + 15.999 = 28.01 g/mol

The final step is to calculate the mass of CO in grams using the mole formula

`\begin{gathered} Mole=\frac{Mass}{Molar\text{ }mass} \\ \\ \Rightarrow Mass\text{ }of\text{ }CO=Mole\text{ }of\text{ }CO* Molar\text{ }mass\text{ }of\text{ }CO \\ \\ Mass\text{ }of\text{ }CO=4.1\text{ }mol*28.01\text{ }g\text{/}mol=114.841\text{ }grams \end{gathered}`

114.841 grams of CO are in a 4.1 mole sample of CO
