How many grams of oxygen `(O_(2))` gas reacts completely with `1.0g` of calcium?

A

`0.6 g`

B

`1.6 g`

C

`4.0 g`

D

`0.4 g`

Text Solution

Verified by Experts

The correct Answer is:
D
`Ca + O_(2) rarr CaO`
According to formula,
Moles of `C` = Moles of `O`
`("Mass"_(Ca))/("Molar mass"_(Ca)) = ("Mass"_(O))/("Molar Mass"_(O))`
`(1g Ca)/(40g Ca) = (m_(O))/(16g O)`
`:. M_(O) = 0.4g`
We can use this approach because the enite `Ca` is changed into `CaO`.
