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

1. 19.6 g

2. 5.71 moles

3. 11.1 moles

Explanation:

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

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

the correct answer would be d. hope this !
