Question

Calculate the number of moles of water lost. (Take the number of grams and convert to moles)

The number of grams is 0.7g​

Answer 1

Number of moles = 0.04 mol

Step-by-step explanation:

Given data:

Mass of water lost = 0.7 g

Number of moles = ?

Solution:

Number of moles = mass/molar mass

Molar mass of water = 18 g/mol

Now we will put the values in formula:

Number of moles = mass/molar mass

Number of moles = 0.7 g/ 18 g/mol

Number of moles = 0.04 mol
