A solution is prepared by dissolving 17.1grams of sucrose, c12h22o11, in 275grams of h20.

a)what is the molar mass of sucrose?

How would i do that??

Use the formula of sucrose to get the mw. You have 12 carbon, 22Hydrogen, and 11 Oxygen atoms per molecule.

To find the molar mass of sucrose (C12H22O11), you need to calculate the sum of the atomic masses of all the atoms present in the compound.

Here's how you can do it step by step:

1. Start by finding the atomic masses of each element in the compound.
- The atomic mass of carbon (C) is approximately 12.01 grams/mole.
- The atomic mass of hydrogen (H) is approximately 1.01 grams/mole.
- The atomic mass of oxygen (O) is approximately 16.00 grams/mole.

2. Count the number of atoms of each element in the compound.
- In C12H22O11, there are 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.

3. Multiply the atomic mass of each element by the number of atoms present in the compound.
- For carbon, 12 atoms x 12.01 grams/mole = 144.12 grams/mole.
- For hydrogen, 22 atoms x 1.01 grams/mole = 22.22 grams/mole.
- For oxygen, 11 atoms x 16.00 grams/mole = 176.00 grams/mole.

4. Add up the masses obtained in the previous step to get the molar mass of sucrose.
- Molar mass of sucrose = 144.12 + 22.22 + 176.00 = 342.34 grams/mole.

Therefore, the molar mass of sucrose is approximately 342.34 grams/mole.

You can use a periodic table to find the atomic masses of elements or refer to online resources that provide accurate atomic mass values.
