Answer:
24dm³
Explanation:
Given parameters:
Mass of CO = 30g
Unknown:
Volume of CO at STP = ?
Solution:
To solve this problem, we need to find the number of moles of CO in the given mass.
Number of moles of CO = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of CO = 12 + 16 = 28g/mol
Number of moles = [tex]\frac{30}{28}[/tex] = 1.07moles
Now;
1 mole of a gas occupies 22.4dm³ volume at STP
1.07moles will occupy 1.07 x 22.4 = 24dm³
