How much water (H2O ) would form if 4.04 g of hydrogen (H2) reacted with 31.98 g of oxygen (O2 )?
Norma-Jean [14]

Answer:

Mass = 36 g

Explanation:

Given data:

Mass of water formed = ?

Mass of hydrogen = 4.04 g

Mass of oxygen = 31.98 g

Solution:

Chemical equation:

2H₂ + O₂   →   2H₂O

Number of moles of hydrogen:

Number of moles = mass/molar mass

Number of moles = 4.04 g/ 2 g/mol

Number of moles = 2.02 mol

Number of moles of oxygen:

Number of moles = mass/molar mass

Number of moles = 31.98 g/ 32 g/mol

Number of moles = 1.0 mol

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

                O₂         :         H₂O

                 1           :           2

                H₂         :         H₂O

                 2          :          2

               2.02       :      2.02

Number of moles of water formed by oxygen are less thus oxygen will limiting reactant.

Mass of water:

Mass = number of moles × molar mass

Mass = 2 mol × 18 g/mol

Mass = 36 g

Can anyone please help me find molar masses of compounds. For example Copper (ll) sulfate (CuSO4)
Alina [70]

Answer:

Explanation:

You would have to add up the atomic masses of all the compounds in the compound, making sure you include how many molecules of each are in the compound

For example, in CuSOA we have 1 molecule of Cu and S, as 4 molecules of O

The atomic masses are as follows:

Cu = 63.55 u

S = 32.065 u

O = 15.99 units

This is how we would add it up:

(Atomic mass of Cu) + (Atomic mass of S) + 4(Atomic Mass of O)

(63.55) + (32.065) + 4(15.99)

(63.55) + (32.065) + 63.96

= 159.575 u
