## How many moles are in C9H8O4?

Ok, C9H8O4 has a molar mass of 180 g/mol divide the 2; 180/41.4 and you end up with mols = 4.347 multiply by avogradros number (6.022e23) and you end up with molecules. **0.150 mole C9H8O4** x = 3.61 x 10 23 O atoms 1 Answer use the molar mass of aspirin to determine how many moles you have in that sample.

## How many moles of C9H8O4 are in a 0.500 g tablet of aspirin?

FREE Expert Solution

Thus, the number of moles of C_{9}H_{8}O_{4} in a 0.500-g tablet of aspirin is **2.8×10 ^{–}^{3} mol**.

## How do you calculate moles in aspirin?

Calculate the moles of substance **by dividing the mass of substance in grams by the molecular weight in amu**. In this case, the aspirin tablet contains 250 mg, or 0.250 g. Therefore, 0.250 g ÷ 180.17 amu = 0.00139 moles of aspirin.

## How many moles of aspirin C9H8O4 contain 0.480 mole of O?

Step-1Given:Moles of O = 0.480 mol O1 mol of C9H8O4 = 4 mol of OThus we can use the conversion factor, 0.480 mol of O = 0.480 mol of O = **0.12** mol of C9H8O4Thus 0.12 mol of aspirin, C9H8O4, contain 0.480 mole of O.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.

## What is the mole of HCl?

Using periodic table you can find molar mass of HCl, which is **36.458 g/mol**.

## How many molecules are in a mole of aspirin?

This means that one mole of aspirin will have a mass of 180.157 g . Now that you know how many moles of aspirin you have in your sample, use the fact that one mole of a substance contains **6.022⋅1023 molecules** of that substance – this is known as Avogadro’s number.

## Why is the purity of aspirin important?

It is important to **ensure that the purified product is actually Aspirin**. This is because if it is not Aspirin, then testing the purity of it will become useless. … When water is added to aspirin, it splits the ester bond that is formed when salicylic acid reacts with ethanoic anhydride.

## How much atoms are in a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = **6.022 × 1023 atoms** • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How many molecules are in a mole?

The mole is represented by Avogadro’s number, which is **6.022×10 ^{23} atoms** or molecules per mol.

## How many atoms are there in 1.50 moles carbon?

Explanation: In the given formula, there is one carbon atom and there are two oxygen atoms. So, in total there are **three atoms**.
