In order to determine how many moles of CO2 provide 2 moles of H2CO3, we must look at the balanced reaction and compare the coefficients of each compound.

CO2 + H2O --> H2CO3

The equation above is already balanced; therefore, for every 1 mole of CO2, we get 1 mole of H2CO3.

2 moles H2CO3  x (1 mole CO2)/(1 mole H2CO3) = 2 moles CO2.

We simply convert the moles of H2CO3 to moles of CO2, which results in 2 moles of CO2 required to give 2 moles of H2CO3.

Suppose you want to create a 6 ng/μL solution in a 25 mL volumetric flask. However, this concentration cannot really be accurate
Over [174]

Answer:

Mass of chemical = 1.5 mg

Explanation:

Step 1: First calculate the concentration of the stock solution required to make the final solution.

Using C1V1 = C2V2

C1 = concentration of the stock solution; V1 = volume of stock solution; C2 = concentration of final solution; V2 = volume of final solution

C1 = C2V2/V1

C1 = (6 * 25)/ 0.1

C1 = 1500 ng/μL = 1.5 μg/μL

Step 2: Mass of chemical added:

Mass of sample = concentration * volume

Concentration of stock = 1.5 μg/μL; volume of stock = 10 mL = 10^6 μL

Mass of stock = 1.5 μg/μL * 10^6 μL = 1.5 * 10^6 μg = 1.5 mg

Therefore, mass of sample = 1.5 mg
