You should have learned the question
m(in g) = n (mole) * M(molar mass)
You need to find the mass of glucose, which the mole of the glucose is given and now you find the molar mass of the glucose which is looking up on a period table and find the average mass of each element and multiple by its number of atom in glucose
M = 12.01 g/mol *6 (for Carbon) + 16.00 g/mol * 6(for oxygen) + 1.01 g/mol *12(for hydrogen)
M = 180.18 g/mol (number may differ a little bit depends on the average mass given on the period table that you have)
Now sub the M=180.18 into the equation m=n*M
m = 1.3 mol * 180.18 g/mol
m = 234.234 g
The mass of glucose is 234.234g and the mass of the mixture is 276g
Simply take the mass of glucose and divide by the mass of the mixture, then multiply by 100
234.234g / 276g = 0.84867
0.84867 * 100 = 84.867%
84.867% ~ 85%
Hope this help!
P.S. I believe this is how you do this question, but I’m not a expert at chemistry, the answer could be wrong. I’m really sorry if it is wrong
