Molar Activity of Compound Solution

Follow our step by step solution on how to calculate Molar Activity of Compound?

FIRST Step Consider the formula

A m = λ \cdot [Avaga-no]

Next Step Substitute values of Variables

∴

A m = 0.0011s⁻¹ \cdot [Avaga-no]

Next Step Substitute values of Constants

∴

A m = 0.0011s⁻¹ \cdot 6E+23

Next Step Convert Units

∴

A m = 0.0011Bq \cdot 6E+23

Next Step Prepare to Evaluate

∴

A m = 0.0011 \cdot 6E+23

Next Step Evaluate

∴

A m = 6.624354836E+20Bq/mol

LAST Step Rounding Answer

∴

A m = 6.6E+20Bq/mol
