Question

What is the mass (g) of 6.50 moles of water (H2O)? While using moleconversion

Answer 1

Mass = 117 g

Step-by-step explanation:

Given data:

Moles of water = 6.50 mol

Mass in gram = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of water = 18 g/mol

Now we will put the values in formula.

6.50 mol = mass/ 18 g/mol

Mass = 6.50 mol×18 g/mol

Mass = 117 g
