A book with a weight of 12 N rests on its back cover. If the back cover measures 0.21 m by 0.28 m, how much pressure does the bo

erik [133]

Answer:

option D = 204 Pa

Explanation:

Given data:

Weight of book = 12 N

Area of book = 0.21 m × 0.28 m = 0.0058 m²

Pressure of book = ?

Solution:

formula

pressure = force / area

P = f/ A

now we will put the values in formula,

P = 12 N/ 0.0058 m²

P= 204 Nm⁻² ( Nm⁻²= Pa)

P = 204 Pa

How many moles are contained in 70. milliliters of a 0.167 M solution of p-toluidine hydrochloride? Enter only the number to two

kramer

<u>Answer:</u> The amount of p-toluidine hydrochloride contained is 2.4 moles.

<u>Explanation:</u>

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}$

Molarity of p-toluidine hydrochloride solution = 0.167 M

Volume of solution = 70. mL

Putting values in equation 1, we get:

$0.167=\frac{\text{Moles of p-toluidine hydrochloride}\times 1000}{70}\\\\\text{Moles of p-toluidine hydrochloride}=\frac{(0.167\times 70}{1000}=2.38mol=2.4mol$
