Question

What is the mass of 1 mole of carbon dioxide? =44What is the mass of 1 mole of oxygen gas (O2)? =32 Percy's goal is to create 22g of oxygen gas in one hour. How many moles of oxygen gas does it need to produce? = 0.7Based on the molar ratios (2:1), how many moles of carbon dioxide must be reacted to create the oxygen required. Round to the nearest tenth. = 1.42CO2 --> 2CO + O2I NEED HELP WITH THIS LAST QUESTION!How many GRAMS of carbon dioxide are needed to produce the 22 grams of oxygen gas in one hour?

Answer 1

mass of CO2 required = 60.5 g

Step-by-step explanation

Given:

`2CO_2\rightarrow2CO\text{ + O}_2`

Molar mass of CO2 = 44 g/mol

Molar mass of O2 = 32 g/mol

Mass of O2 = 22 g

Required: Mass of CO2 needed to produce O2

Solution:

Step 1: Calculate the moles of O2

n = m/M where n is the moles, m is the mass and M is the molar mass

n = 22g/32g/mol

n = 0.6875 mol

Step 2: Find the moles of CO2 using stoichiometry

Molar ratio between CO2 and O2 is 2:1

Therefore moles of CO2 = 0.6875 mol x 2 = 1.375 mol

Step 3: Covert the moles of CO2 to mass

m = n x M

m = 1.375 mol x 44 g/mol

m = 60.5 g
