Here is how the Direct Isotope Dilution Analysis (DIDA) equation looks like.

7.8E-6 = 2E-5 \cdot (\frac{2500 - 1800}{1800})

7.8E-6g = 2E-5g \cdot (\frac{2500Bq/g - 1800Bq/g}{1800Bq/g})

7.8E-6 = 2E-5 \cdot (\frac{2500 - 1800}{1800})

Direct Isotope Dilution Analysis (DIDA) Solution

Follow our step by step solution on how to calculate Direct Isotope Dilution Analysis (DIDA)?

FIRST Step Consider the formula

x = y \cdot (\frac{S i - S f}{S f})

Next Step Substitute values of Variables

∴

x = 2E-5g \cdot (\frac{2500Bq/g - 1800Bq/g}{1800Bq/g})

Next Step Convert Units

∴

x = 2E-8kg \cdot (\frac{2.5E+6Bq/kg - 1.8E+6Bq/kg}{1.8E+6Bq/kg})

Next Step Prepare to Evaluate

∴

x = 2E-8 \cdot (\frac{2.5E+6 - 1.8E+6}{1.8E+6})

Next Step Evaluate

∴

x = 7.77777777777778E-09kg

Next Step Convert to Output's Unit

∴

x = 7.77777777777778E-06g

LAST Step Rounding Answer

∴

x = 7.8E-6g
