Respuesta :

According to the explanation given in the last session, for letter B we will have to find the mass for this solution using the Molarity formula again:

M = n/V

0.290 = n/1.65

n = 0.290 * 1.65

n = 0.478 moles of C3H7NO2

The molar mass of C3H7NO2 is 89.09g/mol

89.09 grams = 1 mol

x grams = 0.478 moles

x = 0.478 * 89.09

x = 42.58 grams of C3H7NO2

In this solution, we have 42.58 grams of C3H7NO2
