What is the mass of frutose also known as fruit (c6h12o6) in a 1.40×10^2ml sample of glucose solution that has a concentration of a 1.23m?

Respuesta :

Answer:

m = 129,96 g

Explanation:

c = n / V

n = c * V

n = 1,23 mol/l * 0,14 l

n = 0,722 mol

n = m / M

m = n * M

m = 0,722 mol * 180 g/mol

m = 129,96 g
