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

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
