Answer:

The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.

An aqueous solution was created by placing 0.018 g of NaCl into a 50 mL volumetric flask and diluting to volume with deionized w

Burka [1]

Answer:

Molarity: 6.2x10⁻³M NaCl

Molality: 6.2x10⁻³m NaCl

Mole Fraction: 1.1x10⁻⁴

Mass% NaCl: 0.036% (m/m NaCl)

Explanation:

<em>Molarity -Moles NaCl / L-</em>

<em>Moles NaCl -Molar mass: 58.44g/mol-</em>

0.018g * (1mol/58.44g) = <em>0.000308 moles NaCl</em>

<em>Liters water:</em>

50mL * (1L/1000mL) = <em>0.050L</em>

M = 0.000308 moles NaCl / 0.050L

<em>Molality -Moles NaCl / kg water-</em>

<em>Moles NaCl = 0.000308 moles NaCl</em>

<em>kg water = 50mL * (1g/mL) * (1kg/1000g) = 0.050kg</em>

m = 0.000308 moles NaCl / 0.050kg

<em>Mole Fraction -Moles NaCl / Moles water+ Moles NaCl-</em>

<em>Moles water = 50g * (1mol/18.01g) = 2.776 moles</em>

Moles fraction = 0.000308 moles NaCl / 0.000308 moles NaCl + 2.776moles water

<h3>Mole fraction = 1.1x10⁻⁴</h3><h3 />

<em>Mass Percent -Mass NaCl / Mass NaCl+Mass Water * 100</em>

0.018g / 50g+0.018g * 100

A waterbed mattress has the following dimensions: 210 cm X 160 cm X 25 cm. The density of water is 62.4lb/ft3. What is the weigh

artcher [175]

<u>Answer:</u> The weight of water bed in pounds is 1850.16 lb

<u>Explanation:</u>

To calculate the volume of cuboid, we use the equation:

$V=lbh$

where,

V = volume of cuboid

l = length of cuboid = 210 cm

b = breadth of cuboid = 160 cm

h = height of cuboid = 25 cm

Putting values in above equation, we get:

$V=210\times 160\times 25=8.4\times 10^5cm^3=29.65ft^3$ (Conversion factor: $1cm^3=3.53\times 10^{-5}ft^3$ )

To calculate the mass of waterbed, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

Density of waterbed = $62.4lb/ft^3$

Volume of waterbed = $29.65ft^3$

Putting values in above equation, we get:

$62.4lb/ft^3=\frac{\text{Mass of waterbed}}{29.65ft^3}\\\\\text{Mass of waterbed}=(62.4lb/ft^3\times 29.65ft^3)=1850.16lb$

Hence, the weight of water bed in pounds is 1850.16 lb
