Question

8. How many moles of carbon dioxide are there in 52.06 g of carbon dioxide?
A) 0.8452
B) 1.183
C) 6.022 x 1023
D) 8.648 x 1023
E) 3.134 x 1025

Answer 1

Answer:

B) 1.183

Explanation:

To convert from grams (mass) to moles, we need to divide by the atomic mass (amu)..

The amu of $CO_{2}$  is 44.008

52.06/44.08 = 1.182966733

This can be rounded to 1.1830 moles of CO2

Answer 2

1.183 moles of carbon dioxide are there in 52.06 g of carbon dioxide.

Explanation:

• Moles of substance are defined ratio of the given mass of the substance to the molar mass of the substance.

Given :

The 52.06 grams of carbon dioxide.

To find :

The moles of carbon dioxide.

Solution:

The mass of carbon dioxide = 52.06 g

The molar mass of carbon dioxide = 44.01 g/mol

The moles of carbon dioxide:

$=\frac{52.06 g}{44.01 g/mol}=1.183 mol$

1.183 moles of carbon dioxide are there in 52.06 g of carbon dioxide.
