​

Answer 1

Answer:

Mark as brainliest

Explanation:

Formula is

No. of moles =( given mass)/ (molecular or molar mass)

FOR CO2

no. of moles = 2400/44

=54.54 moles

FOR OXYGEN MOLECULE

No. of moles =2400/32

75moles

FOR CaCO3

no. Of moles = 2400/ (40+12+(16×3))

= 24moles

FOR MgBr2

No of moles = 2400/ (24+80×2)

= 13.04 moles
