Answer the following questions about the fermentation of glucose (C6H12O6, molar mass 180.2 g/mol)
Yuri [45]

The amount of energy in kilocalories released from 49 g of glucose given the data is -4.4 Kcal

How to determine the mole of glucose

Mass of glucose = 49 g

Molar mass of glucose = 180.2 g/mol

Mole of glucose = ?

Mole = mass / molar mass

Mole of glucose = 49 / 180.2

Mole of glucose = 0.272 mole

How to determine the energy released

C₆H₁₂O₆ →2C₂H₆O + 2CO₂  ΔH = -16 kcal/mol

From the balanced equation above,

1 mole of glucose released -16 kcal of energy

Therefore,

0.272 mole of glucose will release = 0.272 × -16 = -4.4 Kcal

Thus, -4.4 Kcal were released from the reaction

Sodium phosphate dissolves as follows: na3po4(s) → 3na (aq) po4-(aq). How many moles of na3po4 are required to make 1. 0 l of so
bezimeni [28]

The 0.05 moles of Na_{3}PO_{4} required to make 1 L of solution in which the Na concentration is 0. 15 M.

Calculation,

The Sodium phosphate dissolves as follows:

Na_{3}PO_{4}(s) → 3Na^{+} (aq)+PO_{4}^{-} (aq)

To make 1. L of solution in which the  Na^{+concentration is 0. 15 M

The morality  of Na^{+= 0.15 M = number of moles / volume in lit

The morality of Na^{+= 0.15 M = number of moles /1 Lit

number of moles of Na^{+ = 0.15 mole

The mole ratio is 1: 3

It means, the 1 mole of Na_{3}PO_{4}(s) required to form 3 mole of Na^{+

So, to form 0.15 mole of Na^{+  = 1×0.15 / 3 moles of Na_{3}PO_{4}(s)required.

Hence, number of moles of Na_{3}PO_{4}(s) required = 0.05 moles.
