How many moles are in 6.35 g of NaOH

Try figuring it out by using dimensional analysis, and what the sodium thing is, and finding out the conversion for the different things.+

moles = grams/molar mass

2A+3B 3C hOW MANY MOLES OF b ARE REQUIRED TO COMPLETELY REACT WITH 9 MOLES OF A?

Meghan--You should not piggy back on another question. Most of the time we don't see those questions (we think its the answer to the original post). You should go to the top of the page and post a new question.

9 mols A x (3 moles B/2 moles A) = 9 x (3/2) = ?

To determine the number of moles in a given mass of a substance, you need to use the formula:

moles = mass / molar mass

First, you need to find the molar mass of NaOH, which is the sum of the atomic masses of each element in the compound.

The atomic mass of sodium (Na) is approximately 22.99 g/mol, the atomic mass of oxygen (O) is approximately 16.00 g/mol, and the atomic mass of hydrogen (H) is approximately 1.01 g/mol.

So, the molar mass of NaOH is:

(1 * 22.99 g/mol) + (1 * 16.00 g/mol) + (1 * 1.01 g/mol) = 39.99 g/mol

Now, you can use the formula to calculate the number of moles:

moles = mass / molar mass
moles = 6.35 g / 39.99 g/mol

Plugging in the values, you get:

moles = 0.1588 mol (rounded to four decimal places)

Therefore, there are approximately 0.1588 moles in 6.35 g of NaOH.
