Answer:
The concentration of KBr is
Explanation:
From the question we are told that
The mass of KBr is
The molar mass of KBr is
Volume of water is
This implies that the volume of the solution is
The number of moles of KBr is
Substituting values
The concentration of KBr is mathematically represented as
Carbon-6 because it is a neutron number
Answer:
7.5 g of hydrogen gas reacts with 50.0 g oxygen gas to form 57.5 g of water.
Explanation:
Here we have the check if the mass of the reactants is equal to the mass of the products.
