const2013 [10]

Answer:

The answer to your question is 330 g of CHO

Explanation:

Data

Calories needed = 2200 kcal/day

CHO = 60%

Proteins = 15%

Fats = 25%

Grams of carbohydrates needed = ?

Process

1.- Calculate the number of calories  in 60% of 2200 kcal

                      2200 kcal ----------------  100%

                          x            ---------------      60%

                       x = (60 x 2200) / 100

                       x = 1320 kcal

2.- Calculate the grams of CHO

                       1 g of CHO ---------------- 4 kcal

                       x                 ----------------  1320 kcal

                       x = (1320 x 1) / 4

                       x = 1320/4

                       x = 330 g of CHO

Calculate molar mass of H2SO3
Readme [11.4K]
  • The atomic mass of hydrogen is 1.00794 g/mol.
  • The atomic mass of sulfur is 32.06 g/mol.
  • The atomic mass of oxygen is 15.9994 g/mol.

So, the total atomic mass is 2(1.00794)+32.06+3(15.9994)=\boxed{82.07408 \text{ g/mol}}
