The total number of protons in 10g of calcium carbonate is `(N_(0) = 6.023xx10^(23))`

A

`1.5057xx10^(24)`

B

`2.0478xx10^(24)`

C

`3.0115xx10^(24)`

D

`4.0956xx10^(24)`

Text Solution

Verified by Experts

The correct Answer is:
C
`:'` 100 gm `CaCO_(3)=6.023xx10^(23)` molecules
`:.` 10 gm `CaCO_(3)=(.023xx10^(23))/100xx10`
`=6.023xx10^(22)` molecule
1 molecule of `CaCO_(3)=50` protons
`6.023xx10^(22)` molecule of `CaCO_(3)=50xx6.023xx10^(22)`
`=3.0115xx10^(24)`
