In the laboratory you dilute 5.32 mL of a concentrated 6.00 M perchloric acid solution to a total volume of 100 mL. What is the
8_murik_8 [283]

Answer:

0.3192 M

Explanation:

From the question given above, the following data were obtained:

Volume of stock solution (V1) = 5.32 mL Molarity of stock solution (M1) = 6 M

Volume of diluted solution (V2) = 100 mL

Molarity of diluted solution (M2) =?

We can obtain the molarity of the diluted solution by using the dilution formula as shown follow:

M1V1 = M2V2

6 × 5.32 = M2 ×100

31.92 = M2 × 100

Divide both side by 100

M2 = 31.92 / 100

M2 = 0.3192 M

Therefore, the molarity of the diluted solution is 0.3192 M.

Find the final equilibrium temperature when 15.0 g of milk at 13.0 degrees c is added to 148 g of coffee with a temperature of 8
user100 [1]

According to zeroth law of thermodynamics, when two objects are kept in contact, heat (energy) is transferred from one to the other until they reach the same temperature (are in thermal equilibrium). When the objects are at the same temperature there is no heat transfer.

So, at equilibrium, q_{lost}=q_{gain},  q_{lost}= q_{milk} + q_{coffee}

q=m×c×T, where q = heat energy, m = mass of a substance, c = specific heat (units J/kg∙K), T is temperature

q_{lost}= (15X13X4.19)+(148X88.3X4.19), (15+148)X4.19XT_{final}=(15X13X4.19)+(148X88.3X4.19)

T_{final}= 81.37 ° C

Calculează cantitatea de zahăr (C12 H22 O11) în ceaiul de dimineața dacă o linguriță conține 5g de zahăr?
slavikrds [6]

Answer:

Explanation:

Translated:

Calculate the amount of sugar (C12 H22 O11) in the morning tea if a teaspoon contains 5g of sugar?

Given parameters

Mass of sugar = 5g

Unknown:

Amount of the sugar =?

Solution:

A mole is the amount of substance that contains avogadro's number of particles i.e 6.02 x 10²³

Therefore, to find the number of moles contained in the teaspoon of sugar we use the expression below:

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

Molar mass of C₁₂H₂₂O₁₁ = (12x12) + (1x22) + (16x11) = 342g/mol

    Number of moles = \frac{5}{342} = 0.015mol of sugar

or 0.015 x 6.02 x 10²³, 8.8x10²¹atoms of sugar
