Can someone please explain this to me t,t

Oksana_A [137]

Answer:

Theoretical 32.04 g

The precent yeild 87. 39 %

Explanation:

Mole of H2 = m/mw = 4/2 = 2 mol

From the equation

1 mol H2 --> 1/2 mol CH3OH

2 mol H2 -->??

So we have 1 mol Ch3oh

Mass of Ch3oh = mole *Mw = 1* 32.04

= 32.04g >>> the theoretically

For percent yeild = actual / theoretical * 100%

( 28.0/32.04) *100% =

87.93%

Answer:

Number of moles

Explanation:

Using the number of moles in chemical reactions, we can determine the quantity of products and even the reactants that are combining to form them.

The number of moles is derived using the expression below is;

Number of moles = $\frac{mass}{molar mass}$

Once we establish the number of moles of any of the specie given from the mass and molar mass, we can relate it to any other species.
