How many moles are there in 245 g of H2SO4? Use the following mass number: H – 1, S – 32, and O – 16Group of answer choices101.2552.5

To find the number of moles in 245 g of H2SO4, we first need to calculate the molar mass of H2SO4.

The molar mass of H2SO4 is calculated as follows:

• There are 2 atoms of Hydrogen (H) in H2SO4. The atomic mass of Hydrogen (H) is 1 g/mol. So, 2*1 = 2 g/mol.
• There is 1 atom of Sulfur (S) in H2SO4. The atomic mass of Sulfur (S) is 32 g/mol. So, 1*32 = 32 g/mol.
• There are 4 atoms of Oxygen (O) in H2SO4. The atomic mass of Oxygen (O) is 16 g/mol. So, 4*16 = 64 g/mol.

Adding these together, the molar mass of H2SO4 is 2 + 32 + 64 = 98 g/mol.

Now, to find the number of moles in 245 g of H2SO4, we use the formula:

Number of moles = mass (g) / molar mass (g/mol)

So, the number of moles in 245 g of H2SO4 is 245 g / 98 g/mol = 2.5 moles.
