Answer:
c. 77 %
Explanation:
Percent mass (% mass) of solute = mass of solute/mass of solution × 100
According to this question, a mountain dew solution weighing 300grams contains 231 g of sugar. This means that:
% mass of sugar = 231g/300g × 100
% mass of sugar = 0.77 × 100
% mass of sugar = 77%.
The answer is (C) as the definitions states that atomic mass is the number of protons and neutrons.
Hope this helps :).
Let's write the equation
According to law of conservation of mass .
- Mass of products=Mass of reactants
Let required value be x
