<u>Answer:</u> The weight of the box is 18,105 N

<u>Explanation:</u>

Pressure is defined as the amount of force exerted per unit area of surface.

Mathematically,

\text{Pressure}=\frac{\text{Force}}{\text{Area}}

We are given:

Pressure on the box = 1065N/cm^2

Force exerted / Weight of the box = ?

Area of the box = 17.0cm^2

Putting values in above equation, we get:

1065N/cm^2=\frac{\text{Weight of the box}}{17.0cm^2}\\\\\text{Weight of the box}=(1065N/cm^2\times 17.0cm^2)=18,105N

Hence, the weight of the box is 18,105 N

Calculate the mass percent by volume of 330.1 g of glucose (C₆H₁₂O₆, MM = 180.2 g/mol) in 325 mL of solution.
nadezda [96]

Answer: The mass percent by volume is 101.6%

Explanation:

The solution concentration expressed in percent by volume means that the amount of solute present in 100 parts volume of solution.

It is represented in formula as :

mass percent by volume =\frac{\text {mass of solute}\times 100}{\text {Volume of solution in ml}}\%

Given : mass of glucose = 330.1 g

volume of solution = 325 ml

Thus mass percent by volume =\frac{330.1g\times 100}{325ml}=101.6\%

Thus the mass percent by volume is 101.6%

How many moles of Fe are in 235.45g of Fe
Elena-2011 [213]
We are given with an element Iron, Fe, with a mass of 235.45 g. We are tasked to solve for its corresponding molar mass in mol. We need to find first the molecular weight of Iron, that is
Fe= 55.845 g/mol
With 235.45 g sample, its corresponding mol is

mol Fe= 235.45 g x 1 mol/55.845 = 4.22 mol Fe
Therefore, molar mass of Iron is 4.22 mol

How does activation energy affect chemical reactions?
Assoli18 [71]

Enzymes affect the rate of the reaction in both the forward and reverse directions; the reaction proceeds faster because less energy is required for molecules to react when they collide. Thus, the rate constant (k) increases. Figure 3: Lowering the Activation Energy of a Reaction by a Catalyst.

In 1983, a pilot miscalculated the fuel requirement for Air Canada Fight 143 from Montreal to Edmonton. Halfway through the flig
drek231 [11]

Answer:

27,397.23 L would be needed for a successful trip.

Explanation:

The problem gives us <u>the density (ρ) of the fuel,</u> by telling us that there are 803 g of fuel in 1 L, in which case:

ρ=\frac{mass}{Volume}=\frac{803g}{1L}  =803\frac{g}{L}

The required mass of fuel is 2.2 * 10⁴ kg, we can convert this value into g:

2.2 * 10⁴ kg * \frac{1000g}{1kg} = 2.2 * 10⁷ g

We calculate the required volume (V), using the mass and density:

803 g/L = \frac{2.2*10^{7}g }{V} \\V=\frac{2.2*10^{7}g }{803g/L}\\ V=27397.26 L

Thus 27,397.23 L would be needed for a successful trip.
