melamori03 [73]

The volume of apple juice could  a diabetic person drink : 100 ml

<h3>Further explanation</h3>

Given

sugar allowance = 8 g

sugar concentration of apple juice : 8.0% w/v

Required

Volume of apple juice

Solution

The concentration of a substance can be expressed in several quantities The concentration shows the amount of solute in a unit of the amount of solvent.

% w/v = mass of solute (weight) in g / 100 ml solution

So for 8% w/v = 8 g of sugar(solute) in 100 ml of apple juice

Consider the reaction, 2 D(g) + 3 E(g) + F(g) =&gt; 2 G(g) + H(g) When D is decreasing at 0.15 mol/Ls, how quickly is E decreasi
muminat

Answer:

0.023 mol/(L*s).

Explanation:

Equation of the reaction:

2 D(g) + 3 E(g) + F(g) => 2 G(g) + H(g)

Using stoichiometry, 2 moles of D reacts with 3 moles of E and 1 mole of F to give the above products.

1 mole of D will react with 3/2 moles of E.

Delta[D]/delta t = 0.15 mol/L.s

Delta[E]/delta t = (3/2) * 0.15 =

= 0.023 mol/(L*s).
