1.  You have 10 grams of HCl, how many moles of HCl do you have?  
Oxana [17]

Explanation:

36.5gm (Molar mass) = 1mole

1 gram = 1/36.5 mole

10grams =(1/36.5) x 10 moles

= 0.027 x 10 moles

=0.27moles

Calculate how many grams of each product are formed when 4.05g of h2o is used. 2h2o=2h2+o2
NISA [10]

Answer:

Explanation:

Given data:

Mass of water used = 4.05 g

Mass of each product produced = ?

Solution:

Chemical equation:

2H₂O   →  2H₂ + O₂

Number of moles of water:

Number of moles = mass/ molar mass

Number of moles = 4.05 g/ 18 g/mol

Number of moles = 0.225 mol

Now we will compare the moles of water with hydrogen and oxygen.

                             H₂O            :              H₂

                               2               :               2

                           0.225           :           0.225

                           

                           H₂O             :              O₂

                             2                :               1

                           0.225           :            1/2×0.225 = 0.113 mol

Mass of hydrogen:

Mass = number of moles × molar mass

Mass = 0.225 × 2 g/mol

Mass = 0.45 g

Mass of oxygen:

Mass = number of moles ×  molar mass

Mass = 0.113 mol × 32 g/mol

Mass = 3.616 g
