Answer:

Molar mass of acetic acid is 60 g/mol

Explanation:

Look at the formula:

CH₃COOH

We have:

2 moles of C → 12.011 amu . 2 = 24 g/mol
4 moles of H → 1.008 amu . 4 = 4 g/mol
2 moles of O → 15.999 amu . 2 = 32 g/mol

Let's sum the mass of each element

24 g/mol + 4 g/mol + 32 g/mol = 60 g/mol

Ganezh [65]

Answer:

57.48%

Explanation:

Calculate the mass of 1 mole of malachite:

MM Cu = 63.55

MM O = 16.00

MM H = 1.01

MM C = 12.01

$(Cu_{2}(OH)_{2}CO_{3})$

A mole of malachite has:

2 moles of Cu

5 moles of O

2 moles of H

1 mole of C

MW Malachite = 2*MM(CU) + 5*MM(O) + 2*MM(H) + 1 *MM(C)

MW Malachite = 2*63.55 + 5*16.00 + 2*1.01 + 1*12.01

MW Malachite = 221.13

Mass of Cu in a mole of Malachite = 2*MM(CU) = 127.1

Now divide the mass of Cu by the mass of Malachite

$%Cu = \frac{127.1}{221.13} =0.5748=57.48%$
