Question

find the number of molecules in 98g of H2SO4

Answer 1

Answer:

one mole of H2SO4 contains 2 mole of hydrogen each weighing 1g each, one mole of Sulphur weighing 32g and four moles of Oxygen each weighing 16g. When we total them we get 2×1g + 32g + 4×16g = 98gwhich is equal to one mole of H2SO4. 294g of H2SO4is having 29498=3 moles of H2SO4

Answer 2

Answer:

6.022 * 10^23 molecules

Explanation:

Ok, so in this case you would use molar mass to convert grams to moles then use avogadros number to convert to molecules.

98 g * 1 mol/98 g = 1 mol H2SO4 * 6.022 * 10^23 = 6.022 * 10^23 molecules
