Covert 0.200 moles of H2SO4 to grams. Show all work

Convert 102.8 grams of H2O to molecules. Show all work

Convert 200.0 grams of H2O to molecules. Show all work

Answer 1

1. 19.6 g

2. 5.71 moles

3. 11.1 moles

Step-by-step explanation:

In order to convert the moles to grams, either the grams to moles we need the molar mass of the compounds:

• H₂SO₄ → 98 g/mol
• H₂O → 18 g/mol

Let's make the conversions:

1. 0.2 mol . 98g / 1 mol = 19.6 g

2. 102.8 g . 1 mol / 18 g = 5.71 moles

3. 200 g . 1 mol / 18 g = 11.1 moles
