Calculating Moles in 3.00g H2SO4

[G3NEl21C]

1. How many moles in 3.00 g H2SO4?


Ok first off I don't know to find this answer. I want to know how to find it not just being told the answer. Second I'm going to need to know how to calculate this from beginning to end please help?

I understand your desire to fully understand the process of calculating moles in a given substance. Here is a step-by-step guide to help you calculate the number of moles in 3.00 g of H2SO4:

Step 1: Determine the molar mass of H2SO4.

The molar mass of a substance is defined as the mass of one mole of that substance. It is usually expressed in grams per mole (g/mol). The molar mass of H2SO4 can be calculated by adding the atomic masses of its individual elements, which are hydrogen (H), sulfur (S), and oxygen (O). Using a periodic table, we can find that the atomic masses of H, S, and O are 1.008 g/mol, 32.06 g/mol, and 16.00 g/mol, respectively. Therefore, the molar mass of H2SO4 is:

2(1.008 g/mol) + 32.06 g/mol + 4(16.00 g/mol) = 98.08 g/mol

Step 2: Convert the given mass (3.00 g) to moles.

To do this, we will use the formula:

Number of moles = Given mass (in grams) / Molar mass

Substituting the values, we get:

Number of moles = 3.00 g / 98.08 g/mol = 0.0306 moles

Therefore, there are 0.0306 moles of H2SO4 in 3.00 g of the substance.

I hope this step-by-step guide helped you understand the process of calculating moles in a given substance. It is important to note that this method can be applied to any substance, as long as you know its molar mass. If you have any further questions, please do not hesitate to ask.
