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 g of `CaCO_(3)` contain
`=6.022xx10^(22)` Contain `=(6.022xx10^(23))/(100)xx10`
`=6.022xx10^(22) CaCO_(3)` species
No. of protons in 1 molecules of `CaCO_(3)`
`=20+6+3xx8=50`
Total number of protons `=50xx6.022xx10^(22)`
`=3.011xx10^(24)`
