Answer:
10.6 % .
Explanation:
From the question above we can get the following parameters which we are going to use to solve the problem; mass of the solvent, which in this case is water= 55.0 grams and the mass of the SOLUTE which is the vitamin C, C6H8O6 in this problem = 6.50 grams.
Calculating the percent weight we are to divide the mass of the solute by the mass of the solution and multiply it by 100. This can be represented mathematically by using the equation below.
Percent weight= (mass of solute/ mass of solution) × 100.
Note that the mass of the solution is equal to the (mass of solute + mass of solvent) = 6.5 grams + 55.0 grams = 61.5 grams.
Hence, percent weight =( 6.5 grams/ 61.5 grams) × 100.
Percent weight = 0.10569105691 × 100 = 10.5691056911.
Percent weight = 10.6 %.
