If the value of Avogadro's number is 6.0...

If the value of Avogadro's number is `6.023xx10^(23)"mol"^(-1)` and the value of Boltzman constant is `1.380xx10^(-23)JK^(-1)`. The number of significant digits in the calculated value of the universal gas constant is:

Text Solution

Verified by Experts

The correct Answer is:
4
`K=(R)/(N_(A)),R=kxxN_(A)=(1.380xx10^(-23))xx(6.023xx10^(23))`
Since both numbers have four significant digits hence, the result will also have 4 significant digits.
