Answer:
0.895 g/mL
Explanation:
Step 1: Given data
Mass of liquid Z (m): 2.763 lb
Volume of liquid Z (V): 5.93 cups
Step 2: Convert "m" to grams
We will use the relationship 1 lb = 453.59 g.
Step 3: Convert "V" to milliliters
We will use the relationship 1 cup = 236.59 mL.
Step 4: Calculate the density of the liquid Z
The density (ρ) of the liquid Z is equal to its mass divided by its volume.
Answer:
<h2>120 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 8 × 15
We have the final answer as
<h3>120 N</h3>

<u>Given:</u>
Concentration of NaClO = 0.037 M
ka (HClO) = 4.0*10⁻⁸
<u>To determine:</u>
The pH of the NaClO solution
<u>Explanation:</u>
The hydrolysis of the weak base can be represented by the ICE table shown below-
ClO- + H2O ↔ HClO + OH-
Initial 0.037M 0 0
Change -x +x +x
Equilibrium (0.037-x) x x
kb = kw/ka = [HClO][OH-]/[ClO-]
10⁻¹⁴/4*10⁻⁸ = x²/(0.037-x)
x = [OH-] = 9.62*10⁻⁵
p[OH-] = -log[OH-] = -log [9.62*10⁻⁵] = 4.02
pH = 14-p[OH-] = 14 - 4.02 = 9.98
Ans: pH of the solution is 9.98
