1.5 moles of `O_(2)` combines with Mg to form MgO. The mass of Mg that has combined is (Mg= 24)

A

48g

B

24g

C

72g

D

36g

Text Solution

Verified by Experts

The correct Answer is:
C
`2Mg + O_(2) rarr 2MgO`
48gm 1mole
1 mole of `O_(2)` combines with = 48g Mg
`rArr 1.5` mole `O_(2)` combines with = 72 gm Mg.
