Answer: 0.25M
Explanation:
Molarity : It is defined as the number of moles of solute present in one liter of solution.
Given mass of = 73.5 g
Molar mass of = 98g/mol
Volume of solution = 3.0L
Answer:
<u>The temperature difference is</u>
Explanation:
The formula that is to used is :
ΔΔ
<em>where ,</em>
- <em>Δ is the heat supplied in calories = 300cal</em>
- <em> is the mass of water taken = m (assumed)</em>
- <em>Δ is the change in temperature</em>
- <em> is the specific heat of water = </em>
ΔT :
According to the law of conservation of mass, the mass of reactants will be equal to the mass of the products. The mass of products and reactants will only differ during a nuckear reaction
Changing of the physical state of water is not a nuclear reaction. So becoz of that the mass will remain constant without any change.
