Zn(s)+2HCl(aq)= Zncl2(aq)+H2(g)

algol13

<span>There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. We calculate as follows:
</span>
2.5 M HCl = 2.5 mol HCl / L soln

0.306 mol HCl / 2.5 mol HCl/L son = 0.1224 L soln needed

M1V1 = M2V2
18 M(V1) = 2.5 M(0.1224 L)
V1 = 0.017 L of the 18 M solution

A food is initially at a moisture content of 90% dry basis. Calculate the moisture content in wet basis

Anvisha [2.4K]

Answer:

Moisture content in wet basis = 47.4 %

Explanation:

<u>Moisture content expresses the amount of water present in a moist sample.</u> <u>Dry basis and wet basis are widely used to express moisture content. </u>

The next equation express the moisture content in wet basis:

$MC_{wb}=\frac{MC_{db}}{1+MC_{db}}$

<em>where, $MC_{wb}$ : moisture content in wet basis and </em>

<em> $MC_{db}$ : moisture content in dry basis </em>

We now calculate the moisture content in wet basis:

$MC_{wb}=\frac{MC_{db}}{1+MC_{db}}$

$MC_{wb}=\frac{0.90}{1+0.90}$

$MC_{wb}$ = 0.474 = 47.4 % wet basis

Have a nice day!
