Answer:
3) 2.75 mol
Explanation:
2 nh3 + ch3oh → products
From the equation above, it can be deduced that 2 moles of NH3 reacts with 1 mole of CH3OH to form the products.
Since the answer is needed in moles,
First we convert g of NH3 to moles. The molar mass of NH3, using the atomic weights on the periodic table, = N (14.0) + 3H (3 x 1.0) = 17.0 g/mole.
93.5 g NH3 x (1 mole NH3 / 17.0 g NH3) = 5.5 moles NH3
The equation tells us that 2 moles of NH3 reacts with 1 mole of CH3OH.
2 moles of NH3 = 1 mole of CH3OH
5.5 moles of NH3 = x mole of CH3OH
x mole = (5.5 moles of NH3 * 1 mole of CH3OH) / 2 moles of NH3
x = 2.75 mol
