NORTH WITH 20N

To solve this given word problem we can first identify the given and the apt formula to use in this phenomenon: Given: Force = 4, 500 N = 4, 500 kg-m/s^2 Acceleration = 5 m/s^2 
Formula: f=ma 
Derivation: m = f/a 
Solution: 
1. M = f/a 
2. M = 4,500 kg-m/s^2 / 5 m/s^2 
3. M = 900 kg 

Hence, the object’s mass is 900 kg.

How many grams of CaCl2

nordsb [41]

Answer:

$\boxed{\text{110.4 g of CaCl$_{2 }$ and 234.5 g of water}}$

Explanation:

1. Mass of CaCl₂

$\text{Let m = mass of CaCl}_{2}\\\\\begin{array}{rcl}\text{Mass percent} & = & \dfrac{\text{Mass of CaCl}_{2}}{\text{Total mass}} \times 100 \%\\\\32.0 \% & = & \dfrac{m}{\text{344.9 g}} \times 100 \% \\\\\text{32.0 $\times$ 344.9 g} & = & 100 m\\\\m & = &\dfrac{\text{32.0 $\times$ 344.9 g}}{100}\\\\ & = &\textbf{110.4 g}\\\end{array}\\\text{You need $\boxed{\textbf{110.4 g}}$ of calcium chloride}$

2. Mass of water

$\text{Let m = mass of water}\\\begin{array}{rcl}\\\text{Mass of water + mass of CaCl}_{2} & = & \text{Mass of solution}\\m + 110.4 & = & 344.9\\m & = &\mathbf{234.5}\\\end{array}\\\text{The mass of water needed is $\boxed{\textbf{234.5 g}}$}$

How many liters of 1.5 M potassium permanganate could be made if 152 g of the solute are available?

Misha Larkins [42]

Answer:

0.64 L

Explanation:

Recall that

n= CV where n=m/M

Hence:

m/M= CV

m= given mass of solute =152g

M= molar mass of solute

C= concentration of solute in molL-1 = 1.5M

V= volume of solute =????

Molar mass of potassium permanganate= 158.034 g/mol

Thus;

152 g/158.034 gmol-1= 1.5M × V

V= 0.96/1.5

V= 0.64 L

What is the molarity of an acid that is made up of 9.5 moles of HCl dissolved in 1:24 L of water?

KIM [24]

Answer:

7.7 mol/L or M

Explanation:

Molarity is defined as moles of solute over litres of solution. So, in essence, Molarity= moles/litres

or often written as M=mol/L

Here we have 9.5 moles of HCl, and 1.24L of water so we just plug those in equation...

M= 9.5/1.24 = 7.7 mol/L or M
