If the molar mass of ASA is 180.2 g/mol, how many moles of ASA were stated by rhe manufacturer to be present in the tablet tested? (Manufacturer stated 325mg Set up as Conversion factor)

Can someone please show me ho to work it out?

(a) (325mg)(0.001g/1.00mg)=0.325g

The conversion factor is (0.001g/1.00mg)

(b) (0.325g)(1 moleASA/180.2g) = _______moles ASA
Can you pick the conversion factor in this step?

Note: The conversion of 325mg to moles can be done in two separate steps as shown above or in a single "setup":
(325mg)(0.001g/1.00mg)(1 moleASA/180.2g) = ____ moles ASA

thank you GK

Sure! To solve this problem, we need to use the given molar mass of ASA and the mass of ASA in the tablet (given in milligrams) provided by the manufacturer.

First, let's convert the mass of ASA from milligrams to grams, since the molar mass of ASA is given in grams per mole.

1. Convert mass of ASA in the tablet to grams:
Given mass of ASA = 325 mg

To convert milligrams to grams, divide by 1000:
Given mass of ASA in grams = 325 mg / 1000 = 0.325 g

Now, we have the mass of ASA in grams.

Next, we can calculate the number of moles of ASA using the formula:

Number of moles = Mass / Molar mass

2. Calculate the number of moles of ASA:
Mass of ASA = 0.325 g (given)
Molar mass of ASA = 180.2 g/mol (given)

Number of moles of ASA = Mass of ASA / Molar mass of ASA:
Number of moles of ASA = 0.325 g / 180.2 g/mol

Now, we can calculate the number of moles of ASA.

Number of moles of ASA = 0.001802 moles

Therefore, the manufacturer stated that there are approximately 0.001802 moles of ASA present in the tablet tested.

To find the number of moles of ASA stated by the manufacturer, we need to use the molar mass of ASA and the mass of the tablet provided.

Step 1: Convert the mass of the tablet from milligrams (mg) to grams (g):
The manufacturer stated the tablet mass as 325 mg, so we need to convert it to grams by dividing by 1000:
325 mg ÷ 1000 = 0.325 g

Step 2: Calculate the number of moles using the molar mass and the mass of the tablet:
Moles of ASA = Mass (g) / Molar Mass (g/mol)
Moles of ASA = 0.325 g / 180.2 g/mol

Now, we can calculate the number of moles of ASA stated by the manufacturer:
Moles of ASA = 0.325 g / 180.2 g/mol ≈ 0.001803 mol

Therefore, the manufacturer stated that there are approximately 0.001803 moles of ASA present in the tablet.
