The cost of a 5.5kg milkshake if 9.7 ounce milk shake costs $3.45 is $68.915.

Cost of 9.7 ounce milk shake = $3.45

One pound is equal to 16 ounces.

1ounces contain 1/16 pound.

9.7 ounces contain (1/16) × 9.7 pound.

9.7 ounces contain 0.606 pounds.

Cost of 0.606 pounds milk shake = $3.45

1 pound = 454g.

0.606 pounds = 454 × 0.606g

0.606 pounds = 275.12g

1gram = 10^-3 kilo gram

275.12 gram = 275.12 × 10^-3 kilo gram

So, cost of 0.27512 kg milk shake = $3.45

cost of 1 kg milk shake = $3.45/ 0.27512 = $12.53

cost of 5.5 kg milk shake = $12.53 × 5.5 = $68.915

Thus, we calculated that the cost of a 5.5kg milkshake if 9.7 ounce milk shake costs $3.45 is

$68.915.

The mass of the marshmallow is 10.9 g.

The mass of a substance is the quantity of matter present in that substance.

The volume of a substance is the amount of space a given mass of that substance occupies.

The density of a substance is the ratio of the mass and a given volume of that substance.

Therefore, the relationship between mass, volume and density is given below as:

From the data provided:

volume of the marshmallow = 2.75 in³

1 inch³ = 16.39 cm³

volume in cm³ = 16.39 * 2.75

volume of the marshmallow = 45.07 cm³

density of the marshmallow = 0.242 g/cm³

Mass of the marshmallow = volume × density

Mass of the marshmallow = 0.242 g/cm³ * 45.07 cm³

16.67=16.7 pounds of mercury

The measure of how densely a material is packed together is called density. As the mass per unit volume, it has that definition. The mass in pounds of mercury is 16.635 pounds.

The term "density" refers to the ratio between the volume (the amount of space an object or substance occupies) and the mass (the quantity of material it contains). Density can also be defined as the quantity of mass per unit of volume. A dense object is one that is both hefty and small.

Density is the measure of an object's mass per unit volume. Kilograms per cubic meter (kg/m³) is the SI unit for density.

Density = Mass / Volume

13.6 g/mL = (m) / (556 mL)

m = 13.6 g/mL × 556 mL

m = 7561.6 g

1 g = 0.0022 pound

The pOH of a solution that contains the given volume and mass is 1.690.

To calculate pOH of sulfuric acid we must know the moles and concentration.

So, to calculate moles using formula,

moles = mass / molecular mass

Given,

mass = 3.5 g

volume = 1.75 lit

So,

moles of sulfuric acid = mass / molecular mass

Putting values,

moles of sulfuric acid = 3.5g / 98.079 g/mol

moles of sulfuric acid = 0.0357mol

Now to know the concentration we are using the formula,

Concentration of sulfuric acid = moles / volume

Putting values,

Concentration of sulfuric acid = 0.0357mol / 1.75l

Concentration of sulfuric acid = 0.0204 mol/l

pOH + pH = 14

pOH = -log(0.0204)

We can determine the mass of gold using the formula above. This is attainable as follows:

0.05 mole = gold in one mole.

Molar mass of gold = 196.97 g/mol

Mole = mass / molar mass

0.05 = mass / 196.97

Mass = 0.05 × 196.97

Mass of gold = 9.85 g

Hence, the mass of the gold is 9.85 g.
