A sample of citric acid, C6H8O7, has a mass of 22.9 g. What amount, in moles, does this mass represent?
aliina [53]

Answer

C6H807 = 192.124 g/mol

n = m/M

    \frac{22.9g}{192.124 g/mol}

n = 0.119 mol

Explanation:

to calculate amount in moles you need to find the molar mass of citric acid then divide the mass of the acid with the molar mass
